I recently bought an R.F. Sedgley Springfield rifle chambered in .30-06. It has an early Rock Island Arsenal receiver (Serial No.: 449XX). The rifle is complete and in very good overall condition with a mint bore.

Question: there is a three digit number stamped in the barrel channel of the stock and on the underside of the barrel. Is this a Sedgley assembly number? Does it mean anything? ... can you use the number to see when the rifle was converted to a sporting rifle?

Thanks in advance ...
