Thank you for the replies so far.

Do we know with any certainty if this particular aircraft - or indeed this block of aircraft - was delivered to gruppe I or gruppe II of JG11?

It appears that gruppe II did not have any FW190's however the following link indicates that gruppe I did. http://www.cieldegloire.com/jg_011.php

Where would it have been based given it was was manufactured in July 1944 and "found abandoned and stripped in late-fall 1944 in the Rheims RR yard"?

Is the following (taken from the website) likely?

1.7.44 - 26.7.44 Beille 5. JD Fw 190A
26.7.44 - 8.44 Mönchen-Gladbach 5. JD Fw 190A
8.44 - 17.8.44 Bönninghardt 5. JD Fw 190A
17.8.44 - 25.8.44 Dammartin-en-Goele 5. JD Fw 190A
25.8.44 - 28.8.44 Reims 5. JD Fw 190A
