Question about Oil Filters

I have inherited several boxes of oil filters from my late father. They are all Salyer's Stay Ready SRP-PF-4. I am fairly certain that
this is equavlent to a Fram PH4 Oil Filter. I know that they fit Chevy Corvairs, but do they fit anything else?
I've got 48 of these still in their original boxes (12 per case), unused. They've been in storage for years but the rubber seals are still supple. I guess I'll try putting them up on eBay. Anybody know what else they might fit?
