Just did a repair on my "new" box brownie (#2, see post in gallery). The film transport rollers were tight and scratching the film emulsion. It turns out that the two rear rollers were jammed against the body. After using a little time and plier work on it, things are fine now.
Fortunately, I have the "delux" model with three apertures and a good shutter. It is also a 120 film size, which makes things easier to use in general. The Efke 25 was a bit slow, so I'm thinking that the 100 or Ilford's FP4+ might be just the ticket for this camera. Best, tim
