Wich or If
I learned alot of skills watching my dad and then helping my dad sportize old, and at the time not very expnsive or desirable K98's, and even some 03's.
If we knew then what we know now, we would have been as well served to put as many of those things away as we could, and still be sitting on them, however I would not trade the skills I learned working those old and at the time not worth as much as a well done sporter.
Looking at the current prices retail and wholesale, almost any surplus rifle that sells for less $100, and some some that may go as high as $150 are candidates for whatever the buyer wants to do to them.
The current collector grade firearms are going for upwards of 3 to 4 hundred dollars wholesale, I will agree should not be reworked at all.
But a $45 type 44 nagant? what are you hurting? A $99 dollar Mauser?
20 30 years from now people may be saying that should never have been done, but knowledge or skills so gained, to me are worth what every K98 I ever saw being worked, by anyone, would be valued at today, if done right, and with care.
