Looking for help to ID a prop

[tailhookerf18]

I'm trying to ID a propeller I got as a gift. It's 48 inches long by 6 1/2 wide. It is metal clad with 80 or more copper rivets that have been slodered on each blade. The metal on both blades is stamped Hartzell. It is a dark wood, possibly mahogany with 6 bolts at the hub. Hub inner diameter is approx 2 1/2 inches. Stamped into the wood are the following:

317T-48
42111-A

and possibly the letters (so faint as to be almost invisible)

SR
URSIG

Also the number 1 is stamped on one blade and the number 2 is stamped on the other blade.

I thought it might be an airboat prop since it is short and has square tips, but the metal clading is extensive and appears to be very labor intensive. Any clues would be welcome. Thanks.

Welcome to the Forum.

At 48 inches it almost has to be for an airboat or perhaps a snow sled.

Thanks for the reply. With the numbers I could read, I was wondering if the 48 in 317T-48 was for 48 inches in length. I also wondered if the T was for tractor. Would you care to venture a guess as to the age?

Sorry, there is no way I would guess at its age.
