I have for offer the remainder of my Bronica SQ kit:
Bronica 45D - 45 degree prism - makes working off a tripod very comfortable. In nice shape, glass perfect, some scuffs on the outer body. 100 shipped within EU or 100 USD plus shipping elswhere.
Two 6x6 120 backs in excellent shape, one SQ-A one SQ-Ai (e.g. compatible with AE prism, IIRC) - Price 50 per back plus shipping, buy both and get free shipping.
When I had the SQ-a system the 45D was my favorite finder. It is a perfect angle for comfort whether using the camera handheld or with a tripod, makes using camera very comfortable. I also recall that the finder has a built-in diopter adjustment so you don't have to buy the glass diopters to make the view perfectly sharp. Good luck with sale. Bob.
You are right Bob, for me starting to use the prism was a revelation of sorts. I am indeed surprised that no one has grabbed it yet - I know that it took me few months before i "hunted" down this one.
