Hej Robin!
As Snautzer found, there are a number of possibilities, and they certainly look like early Bf 109B/C/D or E or Bf 110C/D/ or E props to me.
One thing that strikes me though is the yellow painted tips - in the Luftwaffe the entire blade would have been RLM 70 Schwarz-Grün wth NO coloured tips. To me it seems then that this aircraft may have been used since by the Svenska Flygvapnet, and painted accordingly.
Can you find out where it was originally recovered and which RSwAF aircraft wre operational in the area?
