Try this site. Also try entering "singer sewing machine birthdate" it will give you lots of sites. I am a Singer collector of sewing accessories, books, sewing machines, etc. I enjoy doing it. I used to have a better site saved, can not find it at the moment. I will keep looking. Email me if you like.

This is a long one to copy and paste, sorry. If you enter "singer sewing machines meekers antiques" in your address window, you will get the above site or near enough to it.

From what I could find, that's a model 28, which was commissioned in a batch of 10,000 on November 29, 1910. Enjoy her :)

Hey! I just tried that link at singers with my old machine and it says 1897. cool!

And I still use it, only thing I can't do with it is sleeves and curves, you need both hands to ease in the fullness and it has a handle to turn at the side. Otherwise - works great!

Built to last.

If I thought I could spend £800 on a computerised embroidery machine that would give that kind of service I'd think about saving up. As it is...

Cheer,
AJ
