I'm wondering if anyone can please give me your opinion on whether Ewald Preis' FW190A-8/R2 "Gloria" from 6./JG300 around September-November 1944 had the Erhohte Notleistung engine boost fitted (which would be indicated by the small yellow circle I've pointed to in the attached photo of another FW190).
I really can't tell from the poor quality photo of Preis' machine though I think I can just just make out a small yellow circle where it should be but I would be very grateful for anybody's input on whether this machine had it or not.
