I am looking at a carbine with serial number 173487 or maybe last digit is 1 ??. It has an early true carbine stock without tool compartment. Rest of gun looks later. No serations on rear sight edges. Low arch block. What else do I need to look at to determine what may be non original parts. Does have 3 notch tumbler. Any way to determine if barrel is correct to action? I am new but would like a carbine with original parts but understand this is very difficult to find. What is depth of rifiling on a very good barrel? Wore out barrel?
thanks in advance!!
