Hi there, i recently bought a nice loking Canon P rangefinder. The thing is, it has what appears to be some light leak problems. (I knew of the problems before i bought it).
The light leaks only appear occasionally, with varied intensity. Sometimes it'll be very bad, sometimes not so bad, and mostly not at all.
Does anybody know what this might be?
The shutter curatins look good, a little bit crinkled but no hard creases or holes etc.
Here are some examples of the problem the previous owner experienced.

Any help would be very much appreciated. I'll probably end up taking it in to get repaired, but i wanted to try and do a little research myself first.
cheers!

I would suspect a misplaced or missing light shield under the top cover.

Try this: cap the lens, open the shutter on "B" and hold the release. Point the camera at a bright light source, place your eye at the film aperture and look around, particularly up toward the area where the small range finder window is located.

You may need to bring your back away from the aperture a touch so you can see the track in which the shutter runs. Move the camera around a bit and see if you can see light bouncing into the frame. It would help to use a finder of your other hand to block and reveal different portions of the front openings to help you see the leak if it is in this area.

You may find a slight modification to the above check will be more revealing and easier to do. Load the camera with a fast B/W film, cap the lens and open shutter on B. Then manually fire a flash gun a number of times all around the camera - you can use a small Maglite torch as the light source. I usually expose a few frames, with the light concentrated on different areas of the body ie finder windows, door seal areas etc. Inspection of the negs will give a clear indication of the source of the leak.

Hi, thanks so much for the replies. Its very much appreciated.
I'll do my best to follow the instructions provided, but i have to say i'm a little lost.
I dont fully understand them. Would anybody happen to have a photo or diagram that might help out a little bit? I can understand if its to much trouble. It'd really help me though.
Thanks again for everyones time.
Cheers
