This sale is for a really excellent condition Fuji GX680 6x7cm Insert for the Roll Film Holder type III N, suitable for use with all GX680 cameras fitted with a type III back.
This mask converts your standard 6×8 III N back to a 6x7cm back giving 10 frames on a roll of 120. If you are shooting 6x7cm rather than 6×8, you need this. Very hard to find. I also have 6×7 focusing screens available to use with this mask, and I also have 6×6 and 645 screens and masks in stock.
This mask has only very minor signs of use, just typical light scuffs. Tested and working perfectly. It will be securely packed for posting.
