Thanks for this research. It is much appreciated. The dataplate on this machine was stamped rather heavy (the lettering has a "swollen" look to it), and the definition on the numbers isn't nearly as precise as on my other A-250 dataplate. Given the options, I'd have to say that the date would be 8-29-11. Thanks again for your input and I'll update my information.
