Janey, I don't understand what you are saying. What are you calling the number plate? I don't think my two 15-91's say that it's a 15 anywhere (that I know of). One has a serial number that starts with JC, which isn't listed anywhere. It was made in Canada (says so on the machine). The other is an AH number.
Explain what you're talking about, please.
