Is this the serial number?
I have a Singer 99K and am trying to find the serial number. I found a plate at the base of the machine that says "EK030669" and on the back is has this "SS AU523024". Is either a serial number? If not, where do I look? Do I take it out of the case and look underneath? It's a snug fit in the case and I don't want to take it out unless I have to and I have to if the serial number is there. I know this machine isn't anything great, but it's the only old machine I could afford and I got it serviced and I love it. I would like to know a little info on it by using the serial number. Any help would be appreciated.
