The problem is, there are damn few, pre-war rebarrelings in second tier guns by the original maker.
Show me an example. The very great majority have been done since the war, by someone else.
Since you "disagree completely" with my post, show me what is wrong with my logic on sleeved barrels?
I think you'll find it is spot on, as long as you are honest, and aren't in the business of selling sleevers...

Best,
