Once you get away from the pure, original collectible, there is no limit. The fact is that few of today's milsurps are really collectible, since there are so many and most have been worked over, rebuilt, parts swapped, etc., years ago. If you are lucky enough to find a nice K.98k, or a mint Persian Mauer, hang onto it and do nothing to it. But the run-of-mill M-N or Spanish Mauser that has already been hacked on, there is no real collector interest.
