Cuerpo de cámara fotográfica telémetro Canon L1 35 mm 1956 vintage. Funciona bastante bien

This would fall into the "User" class of 35mm rangefinders. (at least I think it is an L1--- it doesn't have that designation on the base like another one I had.). It takes Leica screwmount lenses--- (known as LTM)--- and it can be yours for about 1/10 of the cost of an M3.
