A Singer model 31-15 with a serial number starting with AH is worth about $225, depending on the condition. As a sewing machine has to be over 100 years old to be considered an antique, and yours was manufactured in the 1950's, you will have to hold on to it for quite a while before you have a true antique. Match the serial number on your sewing machine with a serial number on one of the three lists the Singer Company posts online (see Resources). This will reveal the year your machine was manufactured. However, lists of serial numbers for machines produced from 1851-1870 are unavailable because the original serial number log books were lost.

1. Where is the model number on my machine? Is it the number stamped on the right front corner on the flat part of the machine?
No. Singer didn't put the model numbers on their domestic machines before the early 1950's, hence the need for this chart. The number stamped on the bed of the machine is the serial number; both letters and numbers.
2. My machine isn't black.
This page is for identifying older black-coloured Singer machines.
3. My machine is black and has a carrying handle built into the top of it with a fold-down arm to the left.
That should be the Model 301.
4. My machine has a fold-down arm to the left but no carrying handle.
That will be the Model 221, commonly known as the Featherweight.
5. My machine doesn't have a fold-down arm or a handle and looks like the Model 66.
It's possible that it could be the Model 201 which has the Paperclip Decal Pattern. There is a lesser possibility that it could be the Model 191 or 206 but they can be identified at the same location and only one design was used on these machines.
6. The bed of my machine isn't rectangular but has a sort-of scalloped edge.
These machines are older than the ones identified here and less common.

7. I think I have a Model 127 or 128 but when the slide plate is pulled out, there's nothing underneath.
Either turn the wheel at the right end of the machine until you see the shuttle or look underneath.
