Krichter,
Concerning KG(J)54: see the final chapter(s) of the book
Kampfgeschwader 54 - Von der Ju 52 zur Me 262
Eine Chronik nach Kriegstage büchern, Berichten und Dokumenten 1935 - 1945
Siegfried Radtke
Schild Verlag GmbH (1990)
It will be a challenge to find that one!
Checkmate
Gelbe 3 / B3+?T Me 262 A-1a, WNr. 17030? III./KG(J) 54

David is a regular poster on this forum, so perhaps he still has some booklets left
Messerschmitt Me 262s of KG & KG(J) units
Luftwaffe over the Czech Territory - 1945 Vol III
David E. Brown, Ales Janda, Tomas Poruba & Jan Vladar
JaPo (2010)
Probably the best and most up to date study of planes and history
Perhaps available through David or see
http://www.japo.eu/home.php
There are different articles or mentions made in different publications (even pictures) dealing of those planes scattered in different publications, but I do not have my list (far from complete) under hands now
Hope this helps,
Philippe
