I was given an erfurt 8mm about 14 yrs ago and put it in the back of my gun cabinet. I pulled it out recently and have been going over it in more detail as I was cleaning it. Noticed every part has the same numbers, even the set screws. It is a Kar 98, SN 4503 stamped on the action, bolt, rear underside of stock, butt plate, metal rings around the stock, front site, rear site, plates on bottom below ammo load area, the set screws, and the lever to pull out so you can get the bolt out. The gun also has a lead chain with a slotted end to drop down the barrel for cleaning. Does not have the sling or a bayonet. Has the bayonet mount though. There are some crown stampings around the receiver or action. There is a, S.Ar.III 236, stamped on the top of the butt plate. What could this gun be worth and is the cleaning chain that came with it part of the gun package? Any comments on what I may have would be appreciated. The gun was given to me from the family of my neighbor who passed away in 97'. He was 91 when he passed and at one time his brother lived him a long time ago. I remember him telling me that his brother was in one of the wars so it may have been his gun.
