Adapter for a Topcon/Exakta lens to Olympus OM Film Camera

Would anyone happen to know if there is a Topcon/Exakta to Olympus OM lens adapter?

There seem to be loads for the modern digital cameras, but I have been unable to find any which I can use on my OM-1n film camera.

Thanks.

Sorry, don't have a definitive answer. Though I did enquire one time about using Exakta lenses on a Pentax, and apparently it's not only a matter of an adaptor for one fitting to another (fairly easy to machine), but there must be the right distance between the lens and the film to still focus correctly. This back-focus varies from one make to another so sometimes it's just not possible for it to work to still focus normally. (Many Exakta lenses also have the unusual side shutter release and stop-down mechanism).

Thanks. Yep, I thought it would be along shot.

Can't do it and still focus to infinity - the Exakta mount has a shorter flange focal distance:
