Dating your vintage Singer sewing machine

9/18/2012

PictureSinger dates by Model number
Sooner or later we all ask the question:

"When was my Singer made?"

It's a simple question and should have an easy answer, right?

The simple answer is that pinpointing an exact date for any vintage Singer can be difficult, due to incomplete, conflicting, and contradictory information.   

But a bit of detective work should help you date your machine to within a 2-3
year period. 

Serial number and model number are necessary to start the process.  Armed with your serial number you can visit Singer's website
which provides the year the serial number was allocated.  Unfortunately, serial number blocks were often hundreds of thousands of numbers.  Depending on the factory it could take a few months, a few years, or a decade for all the numbers to be assigned to individual machines.  



Relying on the allocation date alone can be misleading. 

For example, 401 machines carry an NA or NB serial number.  According to the Singer site, all serial numbers beginning with NA were allocated in 1951 and NB serial numbers were allocated in 1956.  However, the copyright date on the 401 instruction manual is 1959 and the model was marketed from 1959-1961. This gives us a truer date range for a 401 than the allocation date alone.  

On the other hand model 15-91 was marketed from 1933 to 1956 (see chart) and were cranked out in huge numbers in the US and Canada.  Since the more prolific factories (such as Elizabethport) burned through serial numbers faster than Anderson, new blocks were allocated more frequently.   For this reason, the allocation date for a 15-91 serial number is a truer manufacture date than it is for a 401. 

In the past Singer's website offered more detailed dating information than at present.  Some of the old Singer tables are still available on the International Sewing Machine Collector's Society (ISMACS) website. 

Happy Sewing!
Barbara

Where do I find the model number on a 1930s machine? Is there any way to find out what model a Singer is based on the serial number?

Marianne,
Identifying a 1930's machine can be a little tricky because Singer like to use the same casting for the head and then put different components on it and call them different models. And they didn't put model numbers on them. It's possible that Singer could answer your question from the serial number, but not a guarantee since they do not have comprehensive records for every factory.
The best advice I can give is to visit the following website for a wonderful interactive tool to identify your model:

Hope this helps!

What is the difference in model 620 and 635? I see a knob on the lower right that my old 620 did not have. What is the purpose of the knob?
