Looking for imformantion on a wooden propeller with # 78 LxL 56 and #6164

[Dbahnson]

From the markings it's most likely an airboat propeller.

Those often had wide, flat blades with squared-off tips.

Is it an early model and is it worth anything tks

[Dbahnson]

It's probably not "early" (and I moved it into the "modern" category) although there's really no way of knowing when it was made.

Airboat propellers have much less value than aircraft propellers, but are sometimes bought by people who think they're aircraft propellers. Check eBay under "completed listings". You'll often see prices realized there.
