An album of 119 photographs of British aircraft of the Second World War chiefly various models of the Vickers Wellington and Vickers Warwick bombers including many rare and unique prototypes

réf. 116420Many of the photographs appear to have been taken at Vickers' Brooklands factory near Weybridge Surrey the famous banked race track is visible in many images and possibly also at the nearby Royal Aircraft Establishment Farnborough Hampshire. Nearly all are dated ranging from 1937 to 1946. The gelatin silver prints have been cropped to highlight the stationary aircraft; the resulting photographs are in a visually appealing panoramic format with most of them between 55 and 75 mm high some smaller some larger and approximately 190 mm wide. They are loosely mounted from three to five per page under clear celluloid sheets in a later commercial photograph album. The album is neither here nor there; apart from a crease near a short edge of one print the photographs are in excellent condition. Approximately 35 different aircraft are shown each represented by between two and five photographs taken from different angles. The verso of each print carries the inkstamp of the RTP Research and Technical Publications Photographic Section of variously the Air Ministry Ministry of Aircraft Production or Ministry of Supply. These stamps restricting reproduction are completed in manuscript with a reference number and date; at least one image is also stamped 'Secret'. The aircraft shown are: Vickers Wellesley Production; Armstrong Whitworth Whitley; Vickers B1/35 1939 1940 and 1941 models - these are prototypes for the Warwick; Vickers Wellington Mk II with and without experimental turret Mk III Mk IV Mk V Mk VIII an unidentified model with an experimental turret Mk X Mk XI Mk XII Gr Mk IV Mk XVI Mk XVII Mk XVIII and T Mk X; Vickers Warwick Mk I Mk I freighter Mk II ASR Mk I ASR Mk I Tropical C Mk I C Mk III Gr Mk II and Gr Mk V; De Havilland Vampire Mk I Mk II Prototype; Westland Welkin Prototype F Mk I F Mk 2; and Vultee Vengeance Mk I. unknown

Press photograph for the refueling endurance flight attempted by two women aviators

1929réf. 17575Underwood and Underwood n.d. 1929 On January 2 1929 Evelyn "Bobbi" Trout 1906 – 2003 set the women's endurance flight record with a time of twelve hours and eleven minutes. The record didn't last a month however before being beaten by Elinor Smith 1911 – 2010 by over an hour. The next month Trout reclaimed the record with a seventeen-hour flight; in April Smith smashed the record with a time of twenty-six hours. Trout and Smith's rivalry led them to collaboration: while participating in the Women's Transcontinental Air Derby in the summer of 1929 they agreed to attempt a month-long endurance flight. The present photo commemorates their first attempt which took place in November of 1929. Though Trout and Smith were able to successfully refuel the plane while in the air three times mechanical issues grounded them after forty-two hours. They set the women's endurance flight record with the time. The photograph shows aviator Bobbi Trout warming up the motor of a Commercial Aircraft Corporation "Sunbeam" plane at the Los Angeles Metropolitan Airport where Trout and Elinor Smith took off on their refueling endurance flight. The typewritten commentary suggests the headline "BOBBIE sic TROUT AND ELEANOR sic SMITH BURY THE HATCHET IN PREPARATION FOR REFUELING ENDURANCE FLIGHT. Photograph 10" x 8" with leaf of typewritten commentary by Underwood and Underwood adhered to verso at bottom edge. Some toning to edges and verso and some wear to the commentary leaf. Very good. Both Trout and Smith had illustrious aviation careers. Trout set an altitude record for light-class aircraft in June of 1929 and set another women's endurance flight record in 1931 by spending over 122 hours in the air with actress Edna Mae Cooper. Alongside Amelia Earhart Phoebe Omlie Louise Thaden and Blanche Noyes Trout co-founded the Ninety-Nines an organization for women pilots. Trout also co-founded founded the Women's Air Reserve with Pancho Barnes. Underwood and Underwood,

The West Side Y.M.C.A. Airplane School Notebook from 1918

1918réf. 40619New York: Y.M.C.A. Training School 1918. Octavo. Three ring notebook filled with unlined loose-leaf paper. Handwritten notes made by unknown author. Date on first notes paper is Sept. 7th - 1918. The student who kept this notebook included many drawings of implements and mechanical parts of airplanes. Also included in the notebook is "the Compound Nozzle Explained" a short 14 pages pamphlet from 1915. The student punched holes and added it to his course notes. The notebook covers two courses: Airplane Motors with Professor Hall and Plane School with Mr. Chedester. In the back of the notebook there is a bibliography a list of tools needed to apply for positions in an airplane factory and a long list of questions the student recorded to ask after lectures. Several clippings from magazines or other sources are included throughout. The student who kept this notebook would have been well prepared for a career in the U.S. Air Service or in a factory. According to the U.S. Labor Department Training Bulletin see below a graduate of the Y.M.C.A. Airplane Mechanics School could expect to earn between $35 and $50 per week to start up from $12 per week in nonessential industry. The training program lasted for 5 weeks 6 days per week. There was also a night program that lasted for 10 weeks. "The West Side Y.M.C.A. Airplane School was established in November 1917 with the object to supply a crying need for men with some knowledge of airplanes both in the Air Service and in the factories. At that time the Government made a call for 10000 airplane mechanics who were urgently needed for this service. In all probability there were less than 1500 mechanics in the whole country who had any experience with airplanes in the field. The Y.M.C.A. embarked upon an extensive advertising program using newspapers magazines and billboards. The results were most gratifying as the school has always had a waiting list regardless of the increased floor space and additional capacity. Inquire for more details. Y.M.C.A.

Early Aviation Engineering: 1920s Handwritten Technical Manuscript on Aircraft Engine Ignition and Electrical Systems; describing the inner workings of Early airplanes with multiple detailed drawings and descriptions

1920réf. 127751920. Early aviation technical manuscript explaining aircraft engine operation ignition systems and electrical wiring during the formative decades of powered flight. Produced in the early 1920s when aviation technology was transitioning from experimental wartime aircraft to increasingly standardized civil and military aeronautical engineering the manuscript documents the mechanical knowledge required to operate and maintain contemporary aircraft engines and electrical systems. The notebook focuses particularly on ignition circuitry engine starting procedures and performance specifications subjects central to the reliability and safety of early aviation machinery. References to the Jaguar engine a widely used aircraft powerplant of the interwar period situate the manuscript within the technical environment of early twentieth century aviation engineering and aircraft maintenance training. Manuscript aviation engineering notebook. Fourteen handwritten pages with numerous technical drawings and labeled diagrams explaining aircraft systems. The manuscript includes sections describing "general data" relating to aircraft performance characteristics such as speed and weight along with detailed mechanical illustrations including a "main wiring diagram." Several pages explain engine starting procedures and ignition circuitry. One labeled sequence reads: "Jaguar starting. See that both the engine magnets are switched off and that the throttle is in the slow running position. 2. With gas starter. Connect the gas coupling of the starter to the lead to the distributor of one of the two engine magnets. See that H1 lead switch from gas starter mag to engine mag is switched off. 3. Start the gas starter." Another passage describing a technical diagram states: "The ignition system is a highly developed form of battery coil ignition designed as an integral part of the engine. The general layout comprises a direct current generated gear driven from the engine." The manuscript combines written explanation with hand drawn schematics intended to clarify the layout and function of aircraft electrical and ignition components. During the early 1920s aviation expanded rapidly following the technological acceleration of World War I when aircraft design engine power and onboard systems developed at unprecedented speed. Technical manuals and engineering notebooks such as this formed an essential part of the training culture surrounding aircraft mechanics pilots and aeronautical engineers who needed to understand increasingly complex electrical systems ignition mechanisms and engine starting procedures. The attention given to wiring diagrams and ignition circuitry reflects the growing sophistication of aircraft power plants and onboard electrical networks during the interwar period. Surviving manuscript documentation of this kind provides insight into how aviation technology was taught recorded and transmitted during a period when aeronautical engineering was still developing standardized instructional literature. Light handling wear with minor age toning; overall excellent condition. A detailed early technical manuscript documenting the mechanical knowledge underlying inter war aviation technology. unknown
