fascinating and highly detailed pair of original Royal Air Force (RAF) Form 620 Workshop & Laboratory Records. These notebooks belonged to Aircraft Apprentice R.J. Bright (Service No. 539372), who was part of the renowned 34th Entry at RAF Halton during the pre-WWII \"Expansion Period.\"
Technical Content:
These are not mere diaries; they are comprehensive technical manuals handwritten by a trainee Fitter II (Airframes and Engines). The content provides a rare \"boots-on-the-ground\" look at the maintenance of pre-war RAF aircraft, including:
• Engine Diagnostics: Meticulous \"Fault-Cause-Remedy\" tables for aero-engines.
• Systems: Deep dives into Carburation, Magneto timing, Lubrication, and Cooling systems.
• Airframe & Rigging: Detailed notes on \"Flight Routine,\" including the checking and tensioning of bracing wires for biplanes.
• Period Illustrations: Features several hand-drawn diagrams and charts used for troubleshooting.
Historical Significance:
Dated November 1936 (11/36), these books capture the RAF at a turning point. R.J. Bright would have been training on the engines and airframes (such as the Hawker Fury, Hind, and early Hurricane) that formed the backbone of the RAF leading into the Battle of Britain. The inclusion of his Service Number (539372) makes this set a \"researcher\'s dream,\" allowing for a full trace of his wartime service record.
