Unidentified Lancaster part?

Hi,

I bought this gunner trigger and ammo switch as a kid back in the early 80's. I was told at the time it was from a Lancaster. Can anyone verify or have any other ideas as to where it was from?

Four engine bomber, but not Lanc. Early war B17 fortress top turret control. I would very much like to add it to my collection! Fancy a throttle off an F-16?
