Also a working leica meter 3 , Icould use some instructions. there are two triangles one filled in black and one a outline the latter seems to coincide with my other meters.

Quite a few items were made in NY. The "Imarect" finder had the later models in mm. Motors for the M2's were designed by Norman Goldberg in NYC. Soft releases & a number of small accessories. Think lens hoods etc.
