I experience any surprises that I seem to remember. I replaced the curtains, one of the winding gears was seized and I put a new beam splitter in. Nothing too surprising when taking it apart when compared to the other Leica copies, everything was where you’d expect it to be.. The only difference was the lever wind. I actually had more trouble getting into a Tanack camera because it was rear door loading instead of being a bottom loader.
As for the snider camera, no never seen it, even nicca cameras are quite rare here!
