Dickx,

Your situation is a bit confusing, but I will take a stab at it. If the serial is a 6 digit, it will be a INLAND manufacturer - but that would not explain why he was seeing an "S" and a "G". If what he has is a 7 digit serial, the first three of the serial indicates that it is a Saginaw SG carbine. Given that he sees a "G" on the right side, it is PROBABLY probably the Saginaw.

There is an old trick where you place a piece if aluminum foil under the sight (but over the serial). You then use a piece of dental floss stretched tight to rub the top of the foil. It causes the serial number and the manufacturer stamp to be emblossed on the foil. Pull out the foil and read it.

Its hard to judge the value of the carbine without a detailed breakdown, a statement of condition and maybe a few pictures. Being an import, the carbine takes a hit from the collector value standpoint. However, it maybe the world's best shooter. As far as a recommendation as to buy it or not, thats up to you and why you want it. Imports make as good of a shooter as CMPicon's and Bringbacks. I personally would drive the 100 miles if the initial offer was priced right any pictures made it appear to be a shooter.

Good luck...
