This is a 1949 Winchester pre 64 model 70 Sporter barrel chambered in .30 Gov't 06.
The overall condition of this barrel grades as very good to excellent.
Bluing - This barrel retains almost all of its bluing and may have been reblued. The barrel threads are not blued, which generally indicates the barrel finish is original. However, the metal polish appears different than the factory finish (see below)
Metal - The metal of this barrel appears to have a slightly higher polish than a factory barrel. It is attractive, but may not be original. Otherwise, the metal is excellent with no issues.
Bore - Bright and shiny, but a few very slight pits on the lands mid-barrel. 7/10 because of the minor pitting, otherwise this bore would grade at 9/10.
