I'm looking for an Olympus OM camera in non-working condition so I can recover the bayonet mount for the standard Zuiko lenses. This is for a somewhat experimental project

, so I'm looking for something cheap! (Just being honest!)
I have just bought a Toucam, but I have heaps of Olympus OM lenses (and a couple of
working cameras), so the thought has occurred to me that if I can get a bayonet mount off an old Olympus OM camera I can make an adapter to fit the Toucam to my Zuiko lenses for wide field shots...
If this has been done before, let me know... but if not, and you can point me towards a bayonet mount at the right price, it'd be greatly appreciated!
Thanks,
Al.
