Roller ruler -[ SoS ]-

Rollers for 16mm, 35mm, and 70mm film. The 16mm roller, lower right, is from a film synchronizer; the two 35mm rollers and the 70mm one are for film guidance in platter system-equipped projection systems.

 

I decided to throw in the ruler to ratchet up the R-item count. Alas, I realized a little too late I should have instead featured the metric side (a shade over 152mm long, just for the record) given that film widths have always been specified in metric units worldwide.
