Wood prop

[newcub]

I am helping a widow sell some of her husband's aviation item. There is a wood prop that is in excellent condition and as best I can read has the following markings. Have I read them wrong? Do you know what the prop is for?
The prior owner had a white cub with blue strip and metal prop for 40+ years.

Markings:

18928 C (Unsure of the blank space)
DFS 36A MAX RPM 2650 (? about D an F)
LLI 75 (Unsure of LLI)

Any insight?
