Need help please in identifying propeller

[Smartpdx]

Hello All,

I have a propeller I am hoping to get assistance on identifying.

first question is it genuine or some kind or reproduction?

if it is real any help on make, model, age would be most appreciated.

Dimensions are 72" long x 7.5" diameter hub x 5" deep hub

There are number marking on the 3rd picture...not much to go on?

Best regards,

[Smartpdx]

Both the design and the numbering is typical of an airboat propeller.

See this link. Sensenich and Banks-Maxwell were the large producer of these wooden props, which have largely been replaced by composite materials.
