As I understand it, in October of 1943 Smith-Corona made an error in numbering upward of 5000 1903A3 rifles. I found this information on Vi Shooter's M1903 Page (http://www.vishooter.net/SC3.txt). On rifles whose serial numbers should have been in the 4780189 - 4784296 range the second and third digits were apparently reversed. An S-C that I bought from the CMP in 2007 is one of those - 487021x. Like most of the ten examples listed in Vi Shooter's receiver/barrel correlation list, mine has an SC 8-43 dated barrel.

My question is, what other references to this numbering error exist? Have other authors written about it? Has any mention of it been found in factory or government records? Just curious to know how well documented this is. Thanks.
