Kodak Verichrome Safety Film was produced between 1931-1956 when it was replaced by Verichrome Pan. It’s a orthochromatic black and white negative film. This rather rare unopened “Duo-Pak” expired in January 1957 which means it was probably made around two years prior.
Verichrome was made in 116, 120, 616, and 620 formats.

So what was the ASA (ISO) rating on this film?

I don’t know and apparently, these people don’t either… https://en.wikipedia.org/wiki/List_of_discontinued_photographic_films
It may have changed over its long production run starting out slow (but fast for the times) at maybe 25 and in the 1950s maybe 50. There’s no ASA rating on the box. Chris
