So much going on...
In a different thread the OP has elected to turn the item in question into a "working gun".
If I've learned anything recently, it's that I know very little. Sometimes I'm not even sure if Fuff is making a general remark or addressing the item in the OP specifically. From what I can tell from SCoSW, the barrel length in question was not particularly rare, the turn line exists and the box and papers are presumably long gone.
The knowledge of when to hold and not shoot vs. light use vs. "Katie bar the door" would not appear to be available from a book, though the book can provide raw numbers regarding numbers produced. Actually "knowing" that sort of stuff, I'm afraid, takes nothing less than the amount of knowledge that people would gladly pay for regardless.
And, if one is entering the field recently, as many here presumably are,
everything they buy will be "out of pocket" - there will be no "wheeling and dealing" until such time as a "stash" as it were, is accumulated.
So what's one to do if Fuff or Dfariswheel aren't hanging by one's elbow? Sometimes I get lucky - I haven't shot my Colt DS, not because I'm a collector, but more due to the fact I have no .38 brass, and it seems to have doubled in less than two years.
Meantime, somebody coughed up 2,500.00 for a silver plate "aftermarket collectible" that I snagged for 900.00 and I'm wondering if I should wait for someone else to overpay or just fix it up for light duty work.
My oldest S&W is a pre-17 that was apparently fired perhaps 500 times before I came along, has no box or papers but is really pretty and probably won't suffer from being fired another 250 times.
Given all that, I'd still go with "shoot it" though I cheerfully acknowledge that Fuff has forgotten more than I'll ever hope to know. But the OP has already decided so why am I here?
Maybe because I've leaned that the more I learn, the less I know.
