If you remember the problem on rewind was only a problem that only 
occurred on rewinding - needed the tension of the film winding back - so 
it effects all frames (some more than others- depending on the direction 
you are pointing the camera in) but only during rewind - if I took the 
film out in the dark it was always ok. One or two others have reported a 
similar problem. I haven't had it on the replacement camera but I now 
always complete the last wind on stroke as a precaution anyway.

The problem with snapping film only happens when I get carried away and so 
forget I'm reaching the end of the film. If you wind on gently it isn't a 
problem.  IR is on a polyester base which is pretty tough stuff. I'm using 
mainly Fuji negative film which is all on tri-acetate.

Thanks for your suggestions. As you suggest, Loctite would probably solve 
the problem with the rewind lever, but I haven't got round to trying it 
yet. Possibly if I had the right tool to tighten it fully (needs to fit in 
the two little holes on the top) it would also help.
