Need help identifying my vintage keystone sewing machine
I cannot find any information on the web to help identify/find a user's manual/learn more about my grandmother's vintage keystone sewing machine. I am guessing that it is from the 70s, but I could be off.
Any information would be appreciated!!! [ATTACH=CONFIG]424537[/ATTACH] Model SSA-10, serial No. 80072. That's all of the information I could find.
