I've recently run across a Singer 9w (I think-it looks like the one on ismacs) with a serial number of 3161473. I've been told it dates from the 1870's, but nothing I'm finding online backs that up. But nothing I'm finding online tells me when it might actually be from, either. Any of the serial number charts that I'm finding tell me it's from "1900-". Well, yes, I suspected as much >.< All I remember is that there's some murkiness around Singer's merge with W&W, which is what I think I'm seeing evidence of.
So, (hoping your google-fu is better than mine this morning) based on the serial number (unfortunately, I don't have pics, although I may be able to get one in a day or so), can anyone tell me A: Is it a Singer 9w? and B: When (approximately) does it date to?
