Not much available on US Propellers, as the company is best know for making drone props. But among the list of 74 inch props on a list I have there is no "FD" model. Could the stamping be "FB"?

It looks as if all of the 74 inch props were made for 90 or 100 hp engines.

There "should" be some other numbers stamped on it, including the Type Certificate number (TC . . . ).

I moved this to the "Modern" propeller category, as it was likely manufactured long after WW1.
