Hi all, started to get into vintage guns a couple years ago and have focused more on revolvers and woodsmans. I had an opportunity to acquire a Winchester model 62 with serial numbers matching. The barrel is marked 62 with no “a” but it appears to have the larger slide grip which I read was a feature of the 62a model. This gun looks to me to be 100% original an not tampered with so a slide replacement seems unlikely but I am an untrained eye. Can I get some assistance on understanding this rifle? Was it a transition rifle of sorts? The serial number is 1848xx. Also, the condition seems excellent with very minimal bluing wear on sharp edges of the gun. Not sure what I should rate the condition of the gun. The wood is excellent as well with only a few blemishes here or there.
