Sensenich 90 inch

[Contrails70]

I have had a Sensenich 90" 8 hole propeller for about 20 years. Got it from an Estate Sale in north TX with little info other than:
Possibly original equipment on a Fairchild of some sort and held for at least 30 years as one of a couple back up props for the the deceased's crop duster (Stearman I think) but never actually used.
It has the Sensenich decals on one side. The only numbers I can find are etched into the back side of the hub/holes are E4326.
Where should I go to find out more detail/worth(?) of this nice propeller?

It's hard to even guess at a value without more identifying information, and it's rare to see one that doesn't have design number stamped around the hub.

If it's the original length (not cut down) it will be from one of the uses on this list where the number begins with "90" followed by letters and additional numbers.
