Thanks for the speedy info. I will have a look when I get back home. I had always heard that the year / month coding had stopped in 2000, but you have proved that wrong. As for the Canadian brands that I routinely see...... John Woods 90% Sears/Kenmore 5% Other 5% They must have some good marketing up here. Thanks again for the information.
