While no clear records have been retained, it appears that the film was restored using the best available process when the original may be heavily scratched. This process is called “wet-gating” and is still used by the Library of Congress. The new, cleaned print was donated to NWCC , and the original was returned to the Cornelio family. The image below shows the programmed punch paper “timing strip” which controlled the Singer Business Machine used to keep the levels between scenes constant when creating the new print.
The clip below shows the process of wet-gating a film to create a new print, which was done as part of the restoration of the Cornelio Legacy Film.
