Replies to all posts here -- just got up. I have no idea what belongs in the POD series, I just follow what Allan Myers and Dale did. I never saw a master list; they do look incongruous. . The "C" always looked odd there, for sure. I have most of the chips you guys show. Roy's "Y" is nice; I don't have it; it is a little like, in some ways, the cute "X" I show here. Don, yes the breaks were to keep the otherwise small pieces from floating away. I always wondered about how they managed with the POA series D, O, P, etc.
