My friend came across this recently and wants to know if anyone can ID this part? I thought it might be from a SBD or dauntless. Over to you…

Only found out today that this part is from a BENDIX turret. Probably B25.

Hi Peter,
That is an interesting find.
The construction is similar to this single flexible mount from a Canso.

…seems to have handles and trigger ‘paddles’ like the one in CD’s link.
Yes, definitely hand-trainable, and the belt-feeds designed to allow a lot of elevation.
It is highly likely that the PT-Boat version was derived from an aircraft mounting such as the rear gun on an SBD.

.
From the photos its clearly hand operated (twin grips and thumb triggers) and swivel mounted for tilting, I doubt it is for a vehicle but its certainly not for the fixed nose guns etc of a P39 or P63.
actually google is your friend>> see here – it is quite a famous wartime development of a recoil damping device for gunners in bombers such as B-17s? claimed or credited with increasing the hit rate of the gunners?
Smiles – that will teach me to be slow to post while I google and paste it seems others answered the question in anycase

Seems you’ve answered your own question! 😉

Looks like the SBD gun mount seen here..

Doubt it’d be out of an Airacobra- seems to have handles and trigger ‘paddles’ like the one in CD’s link.

Just doing some searching online and it looks alot like the SBD rear gunners gun mounts?

Well the plate says Bell – so could it be part of the mounting system for the twin mgs in the nose of a P39 or P400.
