Poles in the Luftwaffe

[noggin]

I got contacted regarding the history of a Polish man by his grandson. The details didn't quite add up, so I started looking at some photos also included within the email as well as contacting Piotr at the Lista Krystka. Turns out this man hadn't joined 301 Squadron until September 1944 in Italy. One photo showed a close up of him working on an engine, the squadron marking to his left was of 6/ Sturzkampfgeschwader 77. Around 90,000 former Polish Wehrmacht soldiers served in Anders' Second Corps at the end of the war. 30% of the entire corps. Has anybody details of Poles serving in the Luftwaffe or if Sturzkampfgeschwader 77 served in Italy ? He was from Silesia, but since his family still live there and weren't expelled after WW2 I assume he was Polish not ethnic German.
