identifying Unico propeller

[buddy]

thank you, my first post. I am trying to identify a Unico Propeller( or what I believe to be a UNICO due to the below Unit No. 2495) that measures 126 1/2 inches, a propeller shaft hole diameter of 3/1/8,
a hub diameter of 11", a diameter of individual bolt holes of 1/2", a hub thickness of 7/1/4", that is marked Unit No. 2495, Navy No. N78 and U.S. anchor marking. I would be very grateful for any information.

I just bought a very similar UNICO propeller. Also marked NAVY NO. N. 78 (or maybe 73 as it is hard to tell). UNIT NO 2498. 126.5" long.
