Two 400 foot magazines for Debrie Parvo cine camera.

The Debrie Parvo was developed by Joseph Jules Debrie, built by his son Andre Debrie and was a relatively compact camera for the time. The internal magazines were held side by side, with the film fed from the magazine through the gate to a take up magazine through two skewed loops. The Parvo held approximately 400 feet of film inside without the need for an external film magazine, allowing for nearly 6 minutes of film at the standard 16 frames per second silent film rate. It allowed the camera operator to focus the camera lens but had a side optical viewfinder to be used during filming. It was hand-cranked and from 1922 onwards was produced with a metal body.
