Curtiss prop from Martin MB-2

[bob1918]

found this 25 years ago at rural flea market. I paid $400.
It is marker Curtiss propeller co
and around the hub Plane MB-2 Liberty engine 12 and RPM and some other data. Did not touch it other than find a big post in my house and mounted hub on iron pipe. What kind of value do you estimate 25 years later. Thanks

Can you get a better photo of the stamped information, maybe with light coming from the side? I'm not really sure what airplane it was designed for.

All of the numbers stamped on the hub face are important as well.
