Help identifying Nicholas Beazley/Fahlin prop

Hello,

My father recently gave me a Fahlin propeller and was hoping someone could assist in the identification of it. What I do know is that:
1. The prop was manufactured by Fahlin
2. The sticker on the prop states that, “ Manufactured exclusively for Nicholas Beazley Airplane Company”.
3. The prop measures 90” inches in length.
4. Mounting: 3/8" bolt, 8 hole, 1 1/2" spacing
5. Stamped on the propeller face near the center hub:
· DES.385
· NO. 1194
· WB 650

If you know of any information on this type of propeller and what aircraft it was used on I would really enjoy knowing more. Thank you for your time.
