It’s an aileron trim , found it on what was once RAF Sawbridgeworth.
Aircraft that were in use there included Lysander, Tomahawk and Mustang 1.
Any clues people?.

we can write off the Lysander connection as they had ground adjustable only tabs.

The screws appear to be British pattern, with the round head, which are not present on American aircraft.
I think Alan is onto something!

Aha!
Now you see that etched info plate under the Throttles? that is the other part I have, that was found in the area with the trim control.
I just dont understand what they were doing on Sawbridgeworth airfield, unless dismantling took place post war..of which I have already asked locals who tell me no! The lower trim looks to be somewhat similar, I shall have a go with the threads as you suggested
A mystery indeed!

Denis, from reading your p.m., I think you have already been given some fairly accurate info about this unit.
Here is the engine console from a Valetta. The trim units look pretty similar. The same units were also used on the Varsity, but I’m not sure whether they were carried over onto the Viscount, etc.
Nor do they seem to have been used on the Wellington or Warwick, so how yours has ended up on an airfield which you say last saw flying in 1944 remains a mystery.

Your second photo shows better detail and makes me think it might be British made after all.
Are you handy with a spanner and do you know your screw threads? For example, could you (carefully) undo the nut on the bakelite handle to see whether the thread is BA or BSF, etc?
It might help indicate whether the unit is British or American.

What about putting it up on the Aero Part Identity Board forum?

Have you sent a pic to Hendon? They are pretty good with this kind of stuff.

Well it has ‘Port and Starboard’ as opposed to ‘left and right’ Peter. I have been told that P & S is typically British by description.
I have touted this thing around museums & airfairs, I have shown it to just about everyone I have met who has ever sat in an aircraft…and no one recognises it at all!
Here is a slightly better image of the offending article taken in this mornings early sunlight! 🙂

Done, let’s hope it brings forth some info!
(p.s. I did wonder if it might be from a Link Trainer, rather than an aeroplane? Just a thought)

Thought about posting at WIX, someone there will surely recognise it?

I’m bumping this old thread up for a last ditch attempt at identification. Surely someone must know…please….pretty please?:p

The only numbers I can make out are on the actual winding handle, these are: a small circle containing a letter V over what appears to be either an 8 or letter B.
the numbers 49139 13 DS1 are just about legible. not a lot to go on I’m afraid.
By: Whitley_Project - 20th March 2005 at 17:33
What are the part numbers Denis?
