From 2005 to present-day, Singer again changed the dating of serial numbers to a new For all other models from 2005-2011 Singer used the "Culture Management Berlin" list.This still seemed to confuse owners because it would show the allotted quantity and allotted date for each model.The database includes, model, color, serial number, original purchase receipts, instruction manual copyright date and revised dates plus other information that is relevant.With this information I was able to create a "Year of Issue".
After 1900 all models manufactured overseas now included a suffix after the model number to denote the place of manufacture.
Strangely, it included all "NA" and "NB" serial numbers regardless of model number.
From April 1996 to 2005 Singer Customer Service used the Sewing Machine Blue Book dates of 1953-1959 for all "NA" and "NB" serial numbers.
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.
Singer will issue an acknowledgement certificate that you can print out with your name, serial number and year of issue for all Singer model sewing machines.
