"...Why do I never get great deals like this?..." Ever hear the one about the neighbour's widow who said, "Come
take my husbands guns out of my trunk/house."? Said trunk/house(there are several versions of the story) was supposedly full of stuff that went bang, including collector grade stuff. snicker.
"...a standard re-built Carbine..." Yep. That's not a bad thing though. 99.99% of all Carbines went through an arsenal rebuild after W.W. II.
Absolutely give it a really good bath including the stock. IMR4227 is your friend for reloading 110 RN's or HP's. Carbines are great fun to shoot.
Best Carbine site on the 'net is here.
