Hi All, I got an email from my grandpa referencing a Leica C3. He said that my grandma got it as a surprise gift for him secondhand. Looking on google, I don't think it was a C3. Do you all have any idea which camera he might've been talking about? Maybe a IIIc? Maybe a III? Maybe an M3? The M3 looks too modern, as I think this would have been some time in the 1940s. Any thoughts would be appreciated.
