JG 103 pilots in France (1943-1944)

[canonne]

Bonjour,
According to the excellent source: kracker Luftwaffe Archive, these (12) pilots trained with JG 103 in 1943 - 1944. Not sure. Please who could help me to precise the period, the Staffel and the airdrome(s) of their training in JG 103?
1/ Lt Degenhardt Engelbrecht (Engelbert?), ?/JG 103 (dates:? / airdrome :?)
2/ Uffz Deskau Martin, 6/JG 103, (dates:? / airdrome :?)
3/ Oblt Fiby Franz, ?/JG 103, (dates:? before 1943? / airdrome:?)
4/ Uffz Greve Helmut, 3/JG-103, (dates:? / airdrome:?)
5/ Jungnickel Josef, ?/JG 103, (dates:? / airdrome :?)
6/ Lt Kaiser (several pilots with that name), I/JG 103, (dates:? / airdrome:?)
7/ Fhr Meyer Hans Jürgen, ?/JG 103, (dates:? / airdrome:?)
8/ Flg Müller Heinz, ?/JG 103, (dates:? / airdrome:?)
9/ Flg Mutschler Joachim, ?/JG 103, (dates:? / airdrome:?)
10/ Fhj Stadler Christoph, 1/JG-103, (dates:? / airdrome:?)
11/ Fw Streck Eugen, ?/JG 103, (dates:? / airdrome :?)
12/ Suhr Günther, ?/JG 103, (dates: ? / airdrome:?)
I list 242 pilots in Châteauroux (in France) for 1943-1944 period: I am searching for any name of airmen, but also ground crews, mechanics, administrative members, soldiers etc…
All sources are mentioned.
Thank you – Merci
