Erich, I agree with you--The 1st patterns are identical, 2nd patterns though may differ slightly as there were initially at least 2 sets of dies prior to the introduction of the late set (let's say type 2a (like type 1), 2b (very much like type 1 but w/o flaw), 2c (the late type - ray doesn't touch H). I have seen a late type that had an impossibly high number so there was a problem with that one, and raised doubts. I've only seen 3 or 4 examples of these 2c types, and never with a well documented history, but they appear to be a legitimate variant. Erich
