There was nothing wrong done with this rifle. It has been turned into a "fun gun" that will probably see a lot more use than it did before. If some of you "purists" are so concerned about preserving history, why are you shooting these "valuable" relics? After all, every shot fired through the barrel, is wearing the rifle and will eventually make it unsuitable for anything but a worn out wall hanger.
In a way bearhunter, you do have a good point there.
I'm in the Museum business, and preserving heritage is kind of what I deal with on a daily basis.
As a rule of thumb, we consider that we can use specimens for research or education if this use will not risk, more than reasonably, altering the object permanently.
A vintage car Museum curator, with this rule of thumb, can take an old car for a sunny Sunday ride in the country side. But this curator won't weld a huge spoiler on it because it looks cooler and it's the trendy thing to do to blend with the young crowd wearing their baseball cap backwards.
Shooting a "relatively" intact WW1 or WW2 rifle, I consider reasonable; from one year to the next, or from one decade to the next for that matter, if the rifle is well cared for, wear will be negligible.
Drilling holes is, well, a slightly bit more noticeable and permanent. The problem, here, is that even if patched up, it's still too much of a modification.
Yes, I agree that there are quite a few Mosins out there (understatement), and that preservation of this planet's history hasn't been altered a great deal. But, even if the rifle sells well, even if it looks good, even if the work was done well (which was the case here,again I agree), the historical, heritage "###iness" has been drilled away, making that part of the whole milsurp thing lost for that one rifle.
I guess my point is that it's not because it's cheap or abundant that it should be considered insignificant.
