Got one on ebay at a good price but then.. when I opened the film cover, the light seal is gunky all over the inside.
DIYed and scrap through the gunk and replaced it with 1mm black foam cut to size.
Great work in restoring a beautiful camera. I have the RC too, but the lens is a fogged up. Still working well though and have yet to see results from my colour film. Good luck!
I use a new blade hobby knife to sliced the foam with metal ruler. The difficult part is getting the correct width to fit in. I have to redo a few times.
