I have the identical camera, but CLA'd and replaced bellows. I of course paid more than 35 pounds for it. But nonetheless, I love this camera. It is one of my favorites. Slips into the front pocket of pants; has double exposure lock-out. Of course, zone focussing and sunny 16 rule, but that works > 80% of the time for me. My most portable, walk around camera. Then at the end of the day, you get nice big 6x6 negs. Have fun with it.
Might want to check the shutter speeds. Bellows must be good, because you saw no light leaks.
