Hi all, came across a gray paint IIIc (non K serialized) but it oddly has a flash sync right below the flash shoe. Serial number is consistent with other gray paint examples, and it looks like the right shade of gray; both the body and the leatherette. It looks like the flash sync job was done very well, probably by Leica? See attached photos, (it's in pretty decent shape) I'm curious to see what our experts have to say!
Thanks in advance.
