I'm probably of little help - but am just wondering if it's a permanent thing, or just a one-off where the sprockets didn't engage properly with the film? (Or the film wasn't properly inserted in a guide?)

All I can suggest is do a bit more testing to see if you get a better understanding of what's happening - afterall it's just mechanical isn't it?

Cheers

I had this happen to me a few times in the old film days both with 35mm and 6x4.5 cameras. Invariably despite my concerns over the cameras at the time, rushed human intervention often was the root cause.

If you have screwed up a film, why not run that through again as a dummy to check the mechanism and cogs/sprockets are all working correctly, before trying it again with another fresh film. Then give it a go with a live film but purely as a test.

Make sure that there is no button that disables/disengages the winding mechanism as there is on many cameras of this era.

Let us know if it resolves itself?
