Which Aircraft Used This Propeller in 1940?

[Lockehaven]

Hello,

Can anyone tell me which aircraft flying in 1940 would have used the following propeller:

De Havilland Type 4/3, 3 bladed, 2 pitch, non-feathering.

I know for a fact that the Bristol Bollingbrook/ Mk IV Blenheim used it, but what about the Fairey Battle for instance? or any other of the front line RAF aircraft of the time?

As I understand it the Type 4/3 was designed by the US company Hamilton Standard, and manufactured under licence in the UK by De Havilland from the late 1930's onwards.

Thanks for any help.

DH, together with Schwartz and other companies, took out a licence for the Hamilton Standard variable pitch propellor. These propellors saw widespread use on RAF aircraft, including the Hurricane, Spitfire and Battle (all Mk.I variants only). I cannot find which specific variant was used on the Hurricane or Battle, but the Spitfire Mk.I used the Type 5/20.

Thanks Graham,

That helps to narrow it down. If anyone out there knows whether the Type 4/3 propeller was used on the Fairey Battle, Hampden, Whitley, Wellington or any other RAF aircraft with a crew of 3 or more then that would be of particular interest.

Regards.
