Hello,
I spent around $700 or so for this partially-matching Kar98K with the code of 237. It was manufactured by Berlin-Lübecker Maschinenfabrik in 1939. All the markings are intact (two Adlers clutching Swastikas). It's in excellent condition with a cherry stock. It does have electro-pencil import markings (under the barrel and around the receiver).
It came with a manual that calls the rifle "HUNTING CARBINE OF THE MODEL "Mod.98" which seems like it was published in Russia. The seller was a company by the name of Classic Firearms based in North Carolina. I heard they have a dubious reputation. From my experience their service was questionable. I will post photos soon.
However, it seems like the markings or stamps in the manual are not on the rifle itself. Perhaps the manual sent with the rifle was a supplement since there was no original available. It's better to have a manual then no manual.
