My friend Erich,
I checked one finnish book in a store on Luftwaffe in the nordic countries, but nothing found. I asked one Bf 109 fan in the net, and he didnīt know a thin either. SO it is a bit mystery. BUT...this is what I found. English version on that squad, and also on finnish pilots trained for flying Me 109 for night fighter activity in Finland!
