To my knowledge (and I've looked fairly hard) there's not published list of drawing numbers, etc. for S&S props. They made a lot of propellers, many of which became obsolete with introduction of metal variable pitch propellers for certain engines, so lots of S&S props hit the surplus market.

Some models (design or drawing numbers) were also stamped with either engine and/or aircraft usage, so one place to start is right here with the search function. You can also post the stamped data and see if someone recognizes an association.
