l felt the same way about the K98’s as you do the Carcano a few years ago.
I can remember a couple years ago when my Great Uncle Dale, http://www.huntington.edu/News-Releases/All-News/Bronze-Star-Sacrifice/, a WW2 Veteran wanted to look at my WW2 related firearms, so I put a few out the table. He smiled at the M1 Garand, Carbine, 1911 .45 and Thompson M1 ( Kahr Arms reproduction), recalling memories of each until he then made it to the two K98K’s laying at the end of the table and it was stone cold silence afterwards. He picked one of the K98’s and worked the bolt and inspected the rifle, something he didn’t do with any of the American Rifles, and then he dropped the bolt and looked at the bore on that K98k. All the time I was thinking I should have left the German rifles in the safe, he suddenly reinstalled the bolt and slammed it home and then placed the rifle back on the table. He then recalled all the various methods that guys went to send one of the k98’s home as a souvenir and that they should respected as a piece of history like the M1.
As far as Enemy at the Gates movie, the Russians to this day have distrust in any Western produced movie. It is well documented that retreating or even Liberated soldiers or civilians were dealt with.

Stalin lost his son in a German POW camp and Hitler lost a Nephew. Each had a chance to save to their relation and both refused. Russia refused to sign the Geneva convention under Stalin’s direction, Hitler even put out a fig leaf towards Stalin in regards to captive soldiers treatment circa 1942 and Stalin refused stating that all captured soldiers were cowards and traitors.
Germany and Japan still struggle with the past, more in regards with teaching it.

The one thing that my Uncle Dale told me after leaving all the firearms on table, was that “They are all inanimate objects and it still takes one man to kill another, its not so simple to say the rifle alone was responsible, if it was I would have slept better since the end of the war.”
