SeaBass: Numerich is usually pretty good about that stuff but you are buying a surplus bbl and often these things (surplus stuff) are just that, surplus junque (for the collector - LOL).
Lots of times, and most often I would imagine, barrels and other parts are pulled from rifles that are scrap and good for only parts. This would mean to me a buncha wear and barely serviceable stuff.
I would hope Numerich honors your request but I think a replacement might be only a bit better.
Honestly SeasBass, if you are looking to turn that #1 SMLE into a good and accurate shooter, you may want to get a new barrel from a good barrel maker and install that. With a sound action and a new barrel you could make yourself an excellent sporter................. Just my 2 cents worth here though. HTH. Mikey.
