Patrick:
Unless Mr. Bailey learned firsthand that "T" prefix guns stand for "trade" from a knowledgeable official of WR (such as Mr. Clode) I would be careful about the assumption.

Westley's also made G, K, O, E and "delta" prefix guns. What are we to make of those?

I, too, have been to Westley's and talked with the old guard, such a Ken Hulbert. In that regard, I simply urge caution about certain interpretations.

I also own a K gun. "Kremlin"?
