<Yeh, and two, almost three are numbered in succession... how often does <that happen. Plus, those particular machines came from two different <states, and the successive machines were also split up by 900 miles!! <How often does that happen? Early on they were allocated one per store! Also Board part number 1700069A was the first production model, the 1700069D was second and later the 1700069G. The A version required a fair amount of green wire from the factory to make it work. Below 10 and the first are of interest more than the nth copy unless that happend to be the last copy. Allison
