Hello,
I just received a Leica M3 from a moving neighbor, and the camera was given to me in a bag with a few accessories. There were 2 flash units, however, the connectors for the flash units do not have the right connections with the back of the M3. Is there an adapter that needs to be used? Also, I found a copper film canister with the Leitz trademarks on top, a metal winding stud, and a gold Z on the bottom. I assume this was a refillable canister, is there any way to get the film in it developed? I don't think walmart or cvs will know what to do with it.
