JimG, it doesn't matter if it isn't in that group. We would all still like to know more about your carbine. We collect information on ALL carbines. Please fill out a data sheet for it. Every entry we get adds to our knowledge of the carbine and its history. It doesn't matter if it has been through a rebuild or not. It all helps us understand the carbine history. While we are particularly interested in certain serial groups, we are still interested in all carbines regardless of the serial numbers.
