WWI wooden propeller

[Phil Proeto]

Sticker on propeller states FLOTTORP 13066
Both blades alike Grand Rapids, MICH

Design is 7243
45" long
What is the approximate value?

[MWP_Lamar]

At 45" long it is either cut down or it isn't an aircraft prop. Are there any letters among the design numbers? Like perhaps 72A43? If so it's most likely cut down due to prior damage.
