What does "Peter" mean?

Good evening ChrisS, absolutelly no problem.
I know its been a couple of years since your post and all the time new information keeps surfacing, its always difficult deciphering colours from this period as units were constantly changing the colour of numerals, particularly 2 and 5th staffel from red to black etc. I think also this a/c 15+ as been described as having its code painted Brown as well with white outline!

Anders, one wonders why Bretnutz nicknamed his wife Peter? Im sure Martha was pleased with that!

Kindest regs,
Steve.
