There are many resources for machine ID and information, but ya'll are right--every time we lose a big site like Needlebar or Katie Farmer's, it's a sad day in Sewing Machine World.
I've been hunting for some info tonight myself, and am in hopes someone here might know. I picked up an American #1 treadle today, and am trying to find the serial number. This machine does not have the shield-shaped badge with serial # on the front, instead it has a round badge. Ideas? Thanks for any input.
