Thanks Gerd. Interesting that you should post the 12 HP as well. I was afraid the 20 HP might be too large, and so went looking for other references. I found a reference that says MMC showed a 12 HP at a January 1903 show, as well as the 6, 8, & 20 HP models. I'm not sure why my first reference makes no mention of a 1903 12 HP model.
