Of the 13 that I have listed which includes the 7 that Michael had listed, only 3 have serial numbers over 900,000. Two are 1920 NM rifles and one is a 1923 NM rifle. Over half have long slide 48s. I also have an NRA sporter that was sold by Govt in 1928 that has the stock checkered by the S-man. So, he at least was still doing checkering in 1928 but more than half were probably done before 1920. My first one is a real low number with an "05 barrel date but it has a std Lyman 48 so it had to be done after 1920. I've got two low #ed Springfields with RIA 3-18 dated barrels so he must have had a source of new RIA barrels. I would put his approximate time from 1915 to 1930.
