What this tells us is 1 million "NA" serial numbered sewing machines were manufactured in 1951, 1 million "NB" serial numbered sewing machine were manufactured in 1956 and 1 million "NB" serial numbered sewing machine were manufactured in 1961.
This database is the first and only complete database of Singer sewing machines productions in the world.
Copyrights are owned by the Berlin-based agency "Culture Management Berlin".
NA-1951 With the help of so many owners of the Singer 301/301A I was able to come up with a very accurate "Year of Issue" by making a "Database of Serial Numbers" that I collected over the years.
I also used specific events, assorted reference materials, original owner purchase receipts and instruction manual revised dates.
When it comes to Anderson, South Carolina Singer only lists 3 Years of Issue for all NA, NB and NC serial numbers that include Models 301, 301A, 401A, 403A, 500A and 503A.
These years are not completely accurate and are only the years of the entire allotted serial numbers; NA-1951, NB-1956 and NC-1961.
When the Anderson factory started manufacturing the Singer 301 it did not include any suffix on the Model Tag.
This created confusion to where the 301 was actually manufactured and beginning in January 1953 the Model Tag Number now included the suffix "A" to denote it was manufactured at the Anderson, South Carolina, hence the Singer 301A.
A joint licensing agreement for offering this entire database on the Internet, print media is only between the Culture Management Berlin [Germany] and the Singer Corporation NV [USA]. The only production records from the Anderson factory is in 1951 when a limited edition of only 10,000 Singer Model 301 sewing machines were manufactured for the Centennial Year Celebration.
Licenses can be purchased only through the agency "Culture Management Berlin". There are absolutely no production records from 1952 to 1963.
Because of this confusion and in the best interest to owners Singer in 2011 deleted all the records and changed it to the present-day that offers a facility for consumers to uncover the history of their personal Singer household sewing machine and discover the year it was issued.
