Thanks chaps – you are all a bunch of champs.
A google search using the words “bomb release type A-2” yielded success. What I have is actually a “Bomb Release Type A-2”.
How about that?
Mine doesn’t look at all like the pic – it is rusty and has a big hole and dent right in the centre, jamming the release lever, and jagged bits of aircraft frame still attached to the back of it.
According to a couple of warbirds parts sites, this release was fitted to B-17’sand B-24’s.
My grandfather was a farmer near Leybourn, Queensland, Australia, where there was a B-24 base during WWII. I can only suppose he picked it up there.
Prices for a boxed bomb release range from $US8 – $US65, depending on condition.
Needless to say, I prefer mine.
