[BlackCat1982]

Was wondering as they both are units that were at Stalingrad and were they found there ??

Yes the thought had crossed my mind as well, Artillerie Regiment 194 was destroyed there and as this pattern of stamping is made pre 1943 it seems less likely he was one of the alte saltz who might have made up the new Regiment when it reformed. Both nice ekm though!
