I am currently listing on fleabay a spare Graflex '23' Rollfilm back for 5x4 Grafloks - so pretty well most! It's in full working condition and is excellent internally and operationally and good user cosmetically. This back gives a 2 1/4 x 3 in image on 120 film, with eight on a roll. This is the later type with decent rollers and a wind-on lever. Chrome finishes, hinges and the dark slide are all excellent - it's had a good dust-off, but the image makes it look less good than it is. Asking is £75, but any fellow LF forum members will obviously get a preferential price! All sensible offers considered.
