Mamiya Paramender for TLR in exc condition. No rust, operates smoothly. I believe this is a Type 2, but I'm not positive.
The Paramender is used between the camera and tripod for close ups. It adjusts for the difference (parallax) between the viewing and taking lenses. You focus with the viewing lens, then raise up with the Paramender so the taking lens is now in the exact same position as the tripod. I suppose you could do the same thing with a geared column of your tripod if precisely marked - but then you wouldn't have a Paramender.
