This sale is for a near mint condition ETRSi 120 back for the Bronica ETR, ETRS and ETRSi cameras in perfect working order, complete with darkslide.
This back has only minimal signs of use, as can be seen in the photos. Mechanically the back works perfectly, no problems at all.
A great addition for your Bronica ETR 645 outfit – you can never have too many backs! 120 insert included. This is the latest ETRSi version with a crank instead of the thumbwheel for advancing film when loading the back. You will not find a better example in a hurry.
