Mark, As a side note, you were still the strongest signal in the net today, 30-35 over S9. ?You were stronger than Jan. ? As I recall, you have an inverted V; in any case whatever you're using, it's

It seems to me that the Tube Collector's group may have information on how to distinguish the actual manufacturer, done by means of construction, as you point out, and sometimes by markings. Some of
