Ppd-40?

[Wint-O-Green]

So I was wondering today about some of the other weapons that might get added to RO2:HOS, and I remembered my old favorite from RO1; the PPD-40. It wasn't on many maps, and when it was people still preferred the other Russian SMGs to it, but I always liked and used the little guy. So I come here to ask; is there any evidence of PPD-40s in Stalingrad? Some other old RO1 favorites I would like to see that I know were in Stalingrad would be the carbine version of the Mosin-Nagant, and that one shorter version with the permanent bayonet (I forget what they were called), and the Luger. Thoughts?
