A cleaning rod I honestly don’t fault it too hard. Matching cleaning rod is very difficult and it’s generally accepted they don’t often match. To me the spring is the bigger issue. I get asked about a lot of 98k, and what I say, is that never want to have to say “it’s all matching BUT......”
A high quality sling is a couple hundred, Ammo if in the correct box is about $40-50 a box. This gun was sold for a lot during a time when there were zero RCs and not many imported guns floating around. Lots of RC came in satisfying most of the demand. Most guys just want a German gun, matching isn’t their main goal. Me and. Several people have brought in and sold some over the years, but this made guns with an issue go down in price and desirability. I personally still would ad much for a sling and Ammo.
If the band spring matched, I’d say the price is about right for a nice prewar gun.
