Need Help ; searching for owner of uniform

[frei]

Does anyone knows where I can find a list with names of the officers from 4./Gren.Regt.536 from the german 384th inf.div. during the rebuiilding in france during 1943 ?
I have a uniform with some papers in it and searching for many years for the history of the formal owner. Recently I found that the signature on the `Dienstplan` is not from the owner from this uniform but from another officer in the same regiment. I am looking for a leutnant within this regiment who received the Krimschild. The signature on the paper is from a leutnant (Heinz Horbe) who served in the nothern part of russia , schlusselburg/Leningrad region. From all the information I found about this man is that he could not have got a Krimschild !!
So I need to find out who where his college officers. It is difficult but maybe someone can help !!
Here some pictures of the uniform ;








The uniform seems to be made from a russian booty ´tent/poncho´
PS - On the last picture you can see that the owner received 2 medals. Which I don´t know. I put in some loosly for the pictures.
