Default Propeller Manufacturer Identification

Hi, I have a propeller that's been in our family since the 1930's or earlier.
My father always said it was off a Jenny but can't tell.
The markings are,
8'0" x 5'3"
Shop 1469
S C 17488
OX5. (Engine type)?
An A7 stamp with a design, guessing inspection stamp
And a double circle with a three bladed prop and co. at the bottom Again guessing, but can't find a manufacturer that used that design. It looks like a Hartzell Liberty from other photos.

I've also seen some postings with a part of logs from McCook Field showing prop, engine and plane type. Does anyone know how to view those old records?

Thank you for any help
