[schwarze-man]

Hi Mark, I can give some concrete info and some possible info for this blade!
It was fitted to either:
Bf109E with DB601A/N,
Bf110 with DB601A/N or,
ARADO 196 with BMW132K.
The BA 2082 number is the quality inspector stamp.
I am sure the 23.702/2 number indicates that this was blade number 2 on the complete prop assy numbered 23.702.
I believe that the blade individual serial number is 23567.

Lastly, N.Africa....probably 109E.
