Hi all, for MF I have an RB67 which I love but which is a bit of a beast to carry around on the off-chance of getting a picture or two. I recently saw an article about using an old folder, with some nice images and thought it would be something fun to try but I know very little about them. I can print monochrome up to 6x7, so would be looking for something 6x7, 6x6 or 6x4.5 ish and not too expensive, does anyone have any recommendations? I sometimes come across them in junk and vintage shops (usually as an interesting 'display' piece), and am reasonably competent at dismantling things (not so good on the reassembly side) but any pointers as to what to be careful of would be welcome as well. Ta!
