Tested second hand 35mm SLR body from Canon. The body works correctly and was fitted with new light seals. You need to add batteries ( V625U battery needed for the lightmeter ) 

The strap is a part of this set

This camera’s main feature was the first and last of its kind. It was the Copal Square, a vertical-travel, metal-curtain, focal-plane shutter.

The camera’s specifications and ease of use were ideal for aged users. Just press the shutter button for shutter speed-priority TTL automatic exposure. A silicon photocell was used for full-aperture center-weighted averaging metering. Fast shutter speeds from 1/2 sec. to 1/1000 sec. and bulb were mechanically-controlled while slow speeds from 1 sec. to 30 sec. were electronically-controlled.
