It's a Singer model 15-30 manufactured in 1916, judging by the serial number stamped on the machine. This style decal is called "Tiffany" decals. There is a bit of wear on the decals, but not bad. I think with some TLC, it will really be a nice looking machine.
It didn't come with a manual or accessories, so I'll be doing some Google searches & see what I can come up with .
The funny part of this story is yesterday, the same day I bought this machine, we had a power outage. I was really thinking this was an interesting coincidence, since that is why I wanted to get one- the novelty of being able to sew even when the power was out. We are having an ice- storm yesterday & today, but thankfully the power is back on for now.
