I wonder if the drive belt was actually a phosphor bronze band like the ones used on early Atwater Kent radios. Is there a hole in the drive surface of the pulley to fasten the belt with a screw? There seems to be some sort of hole visible in the photo.

Here is a source for the Atwater Kent belts. Perhaps one of these could be modified or used for the purpose?
