Well, the numbers tell you what the diameter is (93") and what the pitch is (76") and that it was used for a Jacobs engine.

Narrowing it down accurately may be difficult without other information. The fact that there are two of them at least suggests that they were removed from a twin engine aircraft and replaced with metal props. One situation where that occurred and resulted in a lot of similar surplus props was the AVron Anson "Bamboo Bomber" with that engine. As I recall, most of those were 90 inches in length, not 93 inches. One easy way to check the stamping is to measure your prop. If it's 90 inches long (+/- a fraction), then it was probably used on that aircraft. The time frame is certainly correct for that model as well.
