Greetings, gang.

Looking for an idea of how to start looking for metal lens hoods for my No. 3 Supermatic shutters with No. 32 Kodak Anastigmat lenses -- I've obtained quite a few metals hoods, but none fits these lenses. Was there a specific model number for either circular or squared hoods that went with these?

Thanks!

Does the Supermatic take a series slip ring? If it's series 6 or 7, Kodak made circular metal hoods to fit them; these used to turn up regularly at camera shows around here, but shows have fallen on hard times, it seems. Have you looked on the 'bay?

Take your favorite caliper or finest graduation marked ruller and measure the Outside Diamater of the front lens barrel. Next look up this measurement in the llist provided in post: http://graflex.org/helpboard/viewtopic.php?t=264&highlight=series+filters .
You will then need to look for a Series ? OD measurement slip on adaptor.
If you want to use step-up ring and threaded filters then post: http://graflex.org/helpboard/viewtopic.php?t=1727&highlight=series+filters will be of help.
