De Havilland Controllable Pitch Airscrew manual

Hi all,

Attaching a scan of the first page and one of the illustrations in a De Havilland maintenance manual I picked up at the Antwerp airport aviation fair last Saturday. Could anyone give me an approximate publication date please?

My guess is late thirties but it would be nice to know a bit more.

TIA

I believe Fokker ordered a number of DH propellers for the Fokker TV.

De Havillands set up negotiations with Hamiltons in 1934 and started production in 1935 so yes your book will be late 30’s. The later Hydromatic commenced production in 1938.
