I am not sure if I am going to or not, but I just got an Agfa folding camera - mine is 6x9 but there are plenty of 6x6's.
Many have seized-up focusing lenses. Mine has a messed up shutter. The lens came off fairly easily, after some research (you just need to know who to ask). I may convert it to PH, but haven't given up on the lens yet. Murray
