Were the props on a Beaufighter the same diameter as on the Halifax? One reference I have says the Beau prop was 12’9″ (3.88m) in daimeter, while another says the Hercules Halifax had 3.9m props.
I’d say that is close enough for government work. I welcome any additional intel.

Merrick quotes type 55/18 for the Mk.III.
Hi
Interesting, wonder where he got his info from.
The AP quoted is 1719C for the III & C.III, issued aug ’43 with ammendments thro’ to dec 45.
So was the 55/18 an earlier prop on the halifax ? or a alternative ? to the de havilland PX.500-1169-T.A.I. ( the manual refers to an AP1538D for specific details on the propeller )
cheers

Thanks. After a little more digging through my refs, I found out that the Halifax III prop was 13′ in diameter, slightly larger that a Beau prop at 12′ 9″.

Hi
AP for beaufighter gives three types of propeller for hercules engined aircraft, types 55/4, 55/14 and 6/6. all 12ft 9in in diameter.
AP for halifax gives type PX.500-1169-TAI, no figure for diameter.
not sure it that helps, merlin halifax AP gives props as 12ft or 12ft 9 ins or 13ft diameter, but these are all type R7/35/–.
Hopefully someone here has the dimensions for the PX.500-1169-TAI
cheers

:diablo::diablo:I don’t know, one 20mm in the right place could make all the difference.
