Just developed a roll from a new to me secondhand rollfilm back. Unfortunatly there is a problem with the mechanism in the winder - i.e. on one or two frames it winds continiously and the automatic interlocks don't engage so I've found I'm having to use the red frame counter window which produces the effect in the attached image. Under examination the window I'd describe as more of a mid-orange, rather than red. . .
Any suggestions on how to remedy this situation, or what use over the window so I can use it as a frame counter?
