B-17F Part from France, but what is it?

[Jennison]

Here's another part, this one from a wreck in France. I wish I had more facts about the Ship, but I don't, at least not yet. The piece was given to me by a renowned B-17 author ( who wrote on the B-17's role in WWII, not technical stuff) so I feel a little bit confident it isn't from a Citroen. But, one never knows until one knows.

Thanks for any help!

It's a turnbuckle with a pair of pin forks.

Turnbuckle one of dozens in every B-17

It's for adjusting the tension of flight control cables ( and other cables) then secured with the jamb nuts and or safety wire. If you can still make out the threads on the rod ends (pin forks) one should have standard right hand treads, and the opposite one should have left hand threads.

Thanks very much. Do you know of any image in the available parts diagrams showing this style of turnbuckle? I couldn't find it in the B-17G manual (I figured whether an E or G wouldn't matter) but neither am I adept at such research.

In the E model catalog, go to Standard Parts and on the first page.... The barrel is an AN155 and the forks are AN161's. The only place that indicates a usage of AN161's is for one aileron control cable. As there are a number of cables within that system, but only one of that set, I suspect that it's used to tension the system.

A set consisting of 2 each AN161's and an AN155 barrel is also known as an AN150 assembly.

I'd posted about this earlier, but I can't for the life of me find that post for some reason. I appreciate the comments and the identification as a turnbuckle. Anyway, I've taken a couple of much better photos of it. In its condition, I haven't yet located any part numbers, but there is the letter "A" on the barrel. Is there any significance to that?

Thanks!

I have merged both threads.
