Hoping for a little help. I am purchasing a Winchester M-1. I found out that on the left side of the barrel says "BLUE SKY, ARLINGTON VA." Was checking around on other forums and the last I saw was from 2003. This rifle has a M-2 bolt in it. Over all the gun is in good condition, however I read that when Blue Sky imported them and put their markings on the barrel it may have messed up the accuracy of the rifle. Anybody have any more info.? Does the Blue Sky on the barrel really effect the value of the gun? by how much? Any thoughts on what The value of the gun may be? he wants $500 for it. Thanks Jim
