I can't find anything on this, please help. I have a Rich's Rotary Electric Sewing machine with a White Sewing Machine Motor on it. I was told White bought Rich's out, but I can find nothing on the internet referencing Rich's Rotary. The machine has a serial number of 127-52721, and up under the machine, embossed in the cast iron is the number 813-5. This is in a cabinet that needs refinishing. Any help will be appreciated, history, value, etc?
