I got my wish - thanks to fellow GBO forum member maglvr44 !
I had opined, in my OP, that I would like to find a .30-30 barrel for my Savage 219B - and he was kind enough to provide me the contact info, for a gunsmith in his area that had one for sale !
It arrived today, and I am more than pleased !
The bore cleaned up into pristine condition, the original longleaf folding sights are still on it, and the bluing is close to 100% except for a bit of fading blue over the chamber - which I took care of in the first half-hour !
[EDIT: Through no one's fault, but my own ignorance, I can't use this .30-30 barrel on my Savage 219B, since it came off a Model 219 (no "B", "C", or "L") and doesn't have or use the cocking stud that protrudes from the side of later ("B/C/L") barrel's locking lugs.
I was unaware that, while later "219 B/C/L", barrels can be used and will function on the earlier 219 rifles, Model "219" barrels will not recock the later "B/C/L", actions for the next shot when broken open.
You see, the early models were striker-fired and toplever-cocked - while the following/later models had the internals changed to a hidden swinging hammer that's cocked via opening the barrel, and has a cocking arm lying inside their right receiver wall just in back of the hinge pin.
So - Into the classifieds it must go !]
