Perfect Circle Piston Rings

Segment of silent film (soundtrack added) produced by/for the Perfect Circle Piston Ring company, circa 1932. Film showcases how they are manufactured at the foundry, being the first piston rings with "individual casting". Specifically, the "85 Oil-Regulating ring with Compensating Channel"

I believe this is from a lost 5-part industrial film series on piston rings titled "Endless Channels", however that film apparently had a soundtrack and this film had none, it was double perf. Really not sure what the story is here- maybe there was a sound-synchronized record version? Perhaps its a work/editing print that made it to the public? Suppose we'll never know. Pretty early days for sound-on-film anyways.

Framerate seemed to be 24 with some 16fps as well, I just rendered it out at 24. Corrected for contrast, exposure, light post-stabilization applied to correct for variance in original print.
