L11CK-43 ID Help

[JustinWB]

I stumbled upon the wooden blade here at the Warrant Officer Carreer College in Ft. Rucker, AL, me and the rest of the Warrants would like to know what aircraft this blade came off of?
The information I have is as follows:

G.B. Lewis CO.
SEP 8087
DES L11CK-43
P.C. 20 T.C. 797

I looked online but could not pin point what type of aircraft, if you can help we would greatly appreciate it.

Thank You
Justin

There are several uses listed. You won't be able to narrow it down any further than that.
