Hello Ben,

I think the reason for your problems with C330f and film transport can be a faulty chin release button... the Mamiya people introduced a "skip-stop" system allowing to use 6 exposure rolls (there were some, maybe some early colur film). You press the chin release button, and turn the handle - and the whole roll goes through without stops! The only way to have this effect is to use a sticking release cable that blocks something in chin release system, or just to press the release button during winding. This is a well-know weak point of all Mamiya TLRs (including mine, of course)

Cheers,
Zhenya
