WWII Propeller Hub inquiry!

msprior01 · 06-01-2017, 08:39 PM

Greetings Forum members,
I have a WWII hub that I am trying to place with the proper engine. I believe it is for either the Continental R-670/Lycoming R-680 or the Jacobs R-755. Here are the engravings: ASSEM 41G 2325 CONT. NO. AC-22790 SER. NO. AC-42-19135.
8 bolts are 7" on center and propeller thickness is 6"
Appears to have 15 center splines.

Are all of these engines interchangeable with this hub?

Any help would be greatly appreciated.

Thanks, Scott

Scott, I think you'd be more likely to find that information by calling Continental or Lycoming, or maybe even an aircraft parts supply like Univair or WagAero.
