Hi,
I have found in a 1920 book*** a listing of specifications by "Bureau of Aircraft Pproduction".
Is anyone knowing where I can read those specifications, particularly those about glueing (14000B, 14020A and 14024), finishing (14008A, 14012 and 14019) and propeller construction in general (29500D) ?
Regards,
PM
