I have a few of these cable release adapters I need to move for Nikon F & F2 and early leica (not sure which Leica models these work with). Works on many older camera shutter buttons without the standard "modern" cable release threads.
Not sure where they were made but I use these and they work fine on my Nikon F & F2.
Lets say $8.00usd each shipped to Conus.
Thanks for looking.
