Bellows look good
Thanks for the replies. I've shined a light from the inside and outside and could not see any leaks.
However, I think I may have found it. I put the back on without the pressure plate, put a light behind the back, set the shutter speed to B and clicked. Looking into the lens I could see a small light to the right (the right if I was looking from the back of the camera) near the bottom. By moving my hand around I discovered that my leak was through the gap where the sliding thing is below the 6x9 window. It turns out that there is a hole, that looks to be original, in the flat plate that slides to block out the 6x9 window. I've taped it up and it looks light tight looking through the front lens. I'll give it another go tomorrow and see.
Thanks again for the replies.
