I think that was used on an Avro Anson, but I'll check on some references if I can find them. S&S seems to have made quite a few of them, some of which I believe are stamped with the aircraft model in addition to the drawing number.
I'd take that to mean that the diameter is 90 inches, the pitch is 80, it was made in 1943 to fit a Jacobs L6 engine in an Avro Anson, perhaps a Mark 2. Here is one of many websites that tell about the plane http://www.bcam.net/ac_rest/anson.htm.
