I just picked this up at one of the local thrift stores today. I think it's a Singer stool. It's walnut and the lid off my other stool fits it perfectly. It's also covered with the same naugahyde as my other stool.
I want to know roughly when it was made and what cabinet it went with. Also, is there a source for that sort of info out there? The machines seem to get more attention than the cabinets they come in.
Here's a couple quick pictures.
Thanks for any help,
Rodney
