singer sewing machine

although i cannot tell you the value i can give you more information on this machine that may help someone else to give you a value.. according to singers records (http://www.singerco.com/pdf/SINGER_G_nos.pdf) this is a model 27. it was manufactured in 1910 in elizabeth new jersey, although the comment section says "st jean, quebec" so im not sure if the new jersey plant ordered it to be made in quebec or if thats for other purposes. and there were only 3000 of them made. hope this helps

I recently purchased a G4 Series machine in good condition. I had it cleaned, replaced the rubber on the bobbin winder, and replaced the leather belt. I called the Singer Company and they supplied a plethera of information about my machine. Mine is a Modle Number 66 manufactured in Germany.

You can order a replacement manual for $15.00 from Singer or download it FREE fromtheir web site. I strongly discourage either option and try to find one second hand or through ebay. Reson being is the photocopy reproduction are poor in quality and the lables for the diagrams are distorted and unreadable.
