On my last few tests with my 'Gift' Yashica FR1 I had some light leaks -- so I have renewed the door seals -- then on last test film small leaks again - maybe from the very narrow seal along top and base of camera back --- as I cannot cut the foam so narrow I have heard that some 'black twine' can be used but cannot find anything like that in the sewing shops here -- can anyone help with ideas ?
