Hello Im looking for most importantly a photo of my grandfather during his imprisonment during WW2. From scarce details I managed to find only these two legit records: link_1! Then he was transfered to: link_2!

I dont know anything more than whats in these links, my father who had more information about him has passed away this year, my mother is not familiar with fathers side of family. All I know is he died years after ww2 ended, in result of lung illness he gotten during his 2 years long sentence. He was lathe-operator and probably its what saved him. Spouse name was Marianna. I cant look beyond sites like ancestry and some polish sites cause I sadly dont know german, and cant read official german camp notes.

Can you please direct me to some available sources, like maybe databases, reports, anything that could lead me his documents?

I`m not sure if its the most apropriate place to ask, please understand.
