I am not into these rare and not so rare codes, without hitting the books, which I will not do. However I think AR is unusual if not rare. I do not find a duffle cut a "downside" its the next best thing besides papers to proof its a 'bring back' which is a big upside! If you want to shoot it the cut can be repaired. A K98k in that condition I would NOT shoot!
I would guess at least 1500 bucks and maybe more to right buyer! Band springs in 1941 most likely were not serialed so that will be an easy replacement. However I really do not keep up with current prices as I no longer can afford them!
There are several dedicated K98k forums on the net, I would go there! Do a Google search.
