Selling WW1 BE2c prop boss.

[toomuchstuff]

Hi, I'm currently selling my propeller boss on Ebay. Sadly I've had no response to my earlier thread & photos on the "Wooden Propellers - Early" section (although over 100 of you have been kind enough to read it). I'd still be really interested to know if anyone has any idea why there are two different L.P. numbers on the boss. I've searched but can't come up with anything. Even an educated guess would be appreciated!
The numbers are LP8074 & LP790, hopefully I've attached a photo.
Many thanks for your time,

Rebecca.
