Old propeller

Hello,
I just bought an old wood propeller and I found the following reference on the hub :
DILLANG (or LANG) PROPELLER
LC (or LQ or LG) 1640
PITCH 1.524
N° 1604

Does anyone have an idea of the date and the type of aircraft on which it was used?

Thank you for your help.

Gilles

Could the "LC" also be an "LP"? The government assigned that prefix to Lang in the teens. I can't tell from those numbers, but a photo and hub dimensions could help identify it.
