We have oval two rails carries the film in camera. End to end lenght of the curve is 30 cms right end to left end.
There should be two things :
1- Wooden dowels which placed in right end and left end for to squeeze film on to the rails
2- Film rolls
How many centimeters distant the film rolls from the two dowels ?
