There are approximately 183 "301" machines on the survey, from NA000019 to NA185406, or about 30% of the total. There are approximately 428 "301A" machines on the survey, beginning with serial number NA186011 to the end, or about 70% of the total. Centennial Badges Nine machines have turned up to date that have the 1851-1951 Singer Centennial Badge on them. They are serial numbers within NA000019 to NA000857. Some are tan shortbed and some are black shortbed (see timeline for details). If you own a 301 with a Centennial Badge that is not included in this list, the data on your machine would be helpful in uncovering the history of these machines.
