Oh BTW What are the exact precautions you take? How do you
clean the felt light trap?
Thanks again Richard

Mostly just with canned air. However, you can also use
sticky tape, like Scotch tape or masking tape to pull grit
off the felt. The problem is that it can also pull some
fibers off the cloth. I Keep the cassettes in a plastic bag
between uses and in cans when loaded. That also helps
because they get a minimum exposure to grit. BTW, I still
have a lot of Kodak cassettes from before they began to
swage the ends on.
Having said this cassettes have a limited life because
they will eventually begin to leak light or scratch the
film.
My Nikon cassettes all came without the spools but I
found conventional plastic spools work OK. I suspect the
originals may have had some sort of fastening on them for
the end of the film, I just use black masking tape.
