And according to that chart, it's a Singer 128, released in a batch of 25,000 on May 23,1919.

I'm not really sure of the value; if it has rare decals it'll be worth more. But there were so many of those machines made, and they were built like tanks, so there are still several thousand of them knocking around in the world. Rarity makes value, and so most of them are NOT rare and not worth the fortune it seems it should be.

The domed wooden case increases the value, assuming it's in good shape. Rare decals in good condition will increase the value. Lots of accessories also helps.

Look at eBay for SOLD Singer 128's and see if you can judge from that. I see a lot of ended listings in the $100-150 range with no buyers, on machines that look quite nice.
