help in identifying propeller

[rainey]

Thank you both for taking the time - although Seattle Eaglerock has very slightly different hub the blades are identical

Alexander Industries refers to the Alexander Eaglerock Biplane built in Colorado in the mid 1920's. There is a very nice example hanging in the Seattle airport with the OX-5 engine and a flared hub Fahlin propeller.

Thanks for the input. That's probably a match. I also noted in my listing that the "2" probably simply refers to the number of blades.

many thanks

I have two listings for Hartzell with that diameter and pitch (104 x 60) but one of them just specifies OX 5 and "special". The other lists OX 5 but includes a note, "Alexander Industries, Ind 2". I have no idea what that indicates.

many thanks for your effort Best Michael

Have attached photos of prop that im trying to figure out - I sent photos and info to Hartzell as they used to be very good but it would appear old guard has retired. They placed it on a Curtiss Robin and attached a grainy photo of said airplane with a similar hub. The only problem that occured to me is the decal ( which is original ) predates the aircraft by about 10 years. The Propeller in Question : 104 1/2 inches , Back of hub 14 1/2 " front in outline of crush plate 6", hub is 4 1/2 ' deep, front bade as noted in photo stamped ox-5 RH other side 7176, back of hub 7176T -Unfortunatly at some point in its life it was refinished but original decals remain.
