Thanks Matti!
Thanks Nick. If I thought the info I had was from a reliable source, I probably would have skipped trying to get confirmation. The gaming forums can be very hit and miss, but given the rest of the info they provided was correct, I'll accept their claim that WNr4436 was Heller's a/c.
The Squadron/Signal and Osprey books and internet were all else I had to go on, and I couldn't see anything there.
Matti, According to the Air Units info at ww2.dk, Steinberger was Kdr III./ZG26 at the time, not a Staka.
Thanks guys
