G.B. Lewis Prop L11B-0 not on list

[zagami]

Hi All,

I just got my first wooden propeller and was happy to find this forum.

Anyway, my prop has the following information, but I don't see it on the G.B. Lewis list that seems to be the comprehensive list online at:
http://www.modernwoodenpropellers.com/GBLewis.htm

Any help decoding the info is appreciated as well. I am totally new to this field. Thanks.

G.B. LEWIS CO.
SER. 11604
DES. L11B-0
P.C. NO. 20
T.C.788

The information on that G.B. Lewis web page is the most current I know of but it's obviously not 100% complete.

I don't have anything else more specific on that either, but the Type Certificate (TC78 applied to a number of different props manufactured by G.B. Lewis, and expired in 1954. I think yours was specifically for a 65 HP engine, but that "narrows it down" to maybe 20 or 30 different possible aircraft.

Thank you Lamar and Dave,

If you can tell me any more about the numbers, even the obvious stuff, it would help as I learn more.

On a side note, there is a fabric (?) covering on the ends of the blades. Sorry, I don't know the terminology for the parts of a propeller. I'm wondering what that material is for. The propeller also has metal covering the business ends of a portion of each blade.

While looking for the names for the parts of a propeller, I found this:

It is helpful, but if you know of other websites that provide rich info like this, I would appreciate knowing about it.

Thanks again.

I just stumbled upon this website of propeller terms. It is for boat props, but do the terms still hold for airplane propellers?

Thanks again.
