Bruce and I talked a bit back when he found the Polishing shops records. RS or Robert Sears left June 30th and no rifles were built between June 25th 1941 to July 8th 1941. There was a clear stopping point for change over and some changes to the wood itself. Start serial on July 8th was 114523 [ which was the 14523 receiver ] I seen some of the Polishing shop ledger and must say stuff like that is really cool. It shows ever serial logged as the last one done that day. Doesn't mean it was a completed rifle but that the receiver was being readied. Rick B
