Alex has spent a lifetime in the sewing industry and is considered one of the foremost experts of pioneering machines and their inventors. He has written extensively for trade magazines, radio, television, books and publications world wide. You may have seen him on The Great British Sewing Bee or How The Victorians Built Britain.


Most of us know the name Singer but few are aware of his amazing life story, his rags to riches journey from a little runaway to one of the richest men of his age. The story of Isaac Merritt Singer will blow your mind, his wives and lovers his castles and palaces all built on the back of one of the greatest inventions of the 19th century. For the first time the most complete story of a forgotten giant is brought to you by Alex Askaroff. Available instantly on Amazon and in paperback.


The simple guide to dating your early Singer sewing machines.



(Where your Singer has two serial numbers always choose the larger of the two to date your machine)



Singer machine serial number dating Guide

(Brace yourself it's tricky!)



Please note this is only a guide, not gospel! Some people mail me to say they have a receipt from 1950 so how could my guide have their machine as made in 1948 or 1949? Let me explain. The production runs at factories like Kilbowie were complex and long. The castings were marked with the serial number during manufacture. The machines were miles from completion, packing and delivery. Then there is delivery to the depot, storage, sales to the shop, and eventually sales to the customer.

These factors all effect the purchase/receipt date, but not the date of manufacture.

For example during WW2 it is a well know fact the Singers were making guns and bullets as well as sewing machines. Only when they could spare the time would they continue with sewing machine production. I have come across a woman who bought her machine brand new in 1946 yet the casting was clearly made in 1939 just before the outbreak of WWII. During World War Two Singer had back orders for over three millions machines!

Now to the dating

All Singers up until 1900 have no letter prefix and came from several factories around the world. The company cleverly managed their production from all factories to coincide with the serial number flow. If you fancy a read on the collapse of Singer in Britain have a go at End of Empire.

Why two serial numbers?

Very early Singers from the 1850's up until the start of prefix letters in 1900 had two serial numbers. There is a lot of controversy over why there were two lots of numbers. The most likely answer is that the larger number was the total number of machines produced by Singers when they only had a few factories and could keep up with, and control, the production output from Britain and America. They would order machines in batches say, 1,000 or 10,000 from Kilbowie, Elizabethport and elsewhere. The lower number may be the total production/batch run of that particular model range, the larger the overall total number of Singer machines made.

Singers have never manage to shed light on these two numbers!

Note: when two serial numbers are on the machine use the larger of the serial numbers.

Anyway here goes nothing. I do hope you find it useful.



On pre-1900 Singer machines if there are two serial numbers, always use the higher, longer, larger, serial number of the two to date your machine.

After 1900 all Singers had a letter prefix before the serial number.

(The letter suffix after the model number denotes where the machine was manufactured)

For example, Singer model 99k serial number Y6307577. The 99k denotes model 99 made in (K) for Kilbowie and the serial number Y6307577 gives us the year of manufacture as 1928.

Singer manufacturing plants and letters

Note: All the letters in BOLD below are letters that come AFTER the model number,
 denoting place of manufacture.

 For example Singer 15K- the K is for Kilbowie.
Singer 211G (model 211 made in Germany)
 Singer 211U (model 211 made in Japan).

This list below can give you an idea for 19th century Singer machines. By the 20th century (after 1900) all Singer machines had a letter before the serial number.


Here are a few of the Singer factory letters around the world. These letter are before the serial numbers. Read the note below these letters...

For some unknown reason the Singer page above had a piece of faulty information, serial letters JA, JB, JC, JD, JE above should be St John, Quebec, known today as St. Jean sue Richelieu.

Hi Alex.

Thanks to your website, I have been able to date my $2 Trash and Treasure Singer as a 1939 model, manufactured in Scotland. It needed a good soaking in kerosine after I bought it about 12 years ago, but it continues to give good service in my workshop/garage. Thanks for the research you have done.


Brian Harris 

Hello Alex,
I have tried a lot of places to date my singer and finally ran into your website. I found mine was made in 1897.  Thank you so very much for all the hard work you put into setting up your page.   


Well that's it, I do hope you enjoyed my work and found it useful. I spend countless hours researching and writing these pages and I love to hear from people so drop me a line and let me know what you thought: alexsussex@aol.com
