Film Speed

I recently discovered 2 brownie cameras at a relatives house and they

each had film in them. I would like to get them developed, but I

don't know what speed the film was, or how I could get it developed.

Is there a standard speed film the cameras used around the 1940's to

1950's? Can anyone offer any advice on getting this film developed?

Thanks in ad

I just remembered the film said "Panachrome" on it and the Patent Date

on the Brownies was 1916. Hope this helps
