Hello,

I found a box of film rollers in my grandfather's attic, and I thought I'd try to find a home for them before I pitch them in the recycle bin. I have maybe a dozen of each size.

I don't know much about them, but here is what I do know:

~ They are clearly for 35mm and 70mm film, and both sizes appear to have a pitch of about 0.18 according to my cheap calipers.

~ The 70mm rollers have 33 teeth

~ The 35mm rollers have 24 teeth

~ The shafts are about 0.3 and the rollers have some pretty amazing bearings in them.

~ Both sizes have a timing belt style pulley on them

Does anyone know what these are? Anyone have any use for them?
