Exa 1 light leak

I have an old 35mm camera, Exa-1. This is the camera:


The problem is light leaks, this is a picture taken with the camera:


I have search the internet, and the Exa-1 does not use light seals.. Anyone familiar which problems will cause such light leaks as this? Thanks!

You might try exakta.org or captain jacks exakta site. It might be a light leak from the bottom, I would try some duct tape on the bottom first to exclude that. The Exa's I have use the mirror as the shutter, hence the slow top speed. to see if something is getting through there try a bright light with the shutter both cocked and in the uncocked position. I actually love these cameras even though I'm not left handed and exakta lenses are good and cheap. I have stopped a light leak from the bottom with bits of black felt glued to the camera.
