If the suffix application digit was being added after engine assy. this is sure news to me and glad we've beaten this one out! . As I've always understood the whole engine date/suffix was done w/ one gang-stamp hit....I wonder what all motors they did this added application digit on? . It's a good one to know too as a help spotting fake stamps since the dupsters would line up all the digits in one gang-stamp and Wham!
As far as the XX pad picture goes I'd have to move a mountain to get near it. . There's a whack of old racing snowmobiles in the way also old race car parts including a nose from a Kremer Bros. 962 Porsche....crazy what a fella ends up with! . I'd be interested what Verne knows though. ~ Pete
