A nice piece of Japanese engineering, in the original box, plastic container and with instruction. This Signal signed invention is a external camera timer for older pieces that had no timer on them (yet). It could be used with a distance cable or be screwed directly into the camera hole. It looks like it was never used and the mechanics seem to work as they should. The snug fitting case measures about 9,5 cm or 3 3/4 inches wide. Check out the video for some vintage camera collecting!
