Good question indeed George--I trust Mr. Hughes as I would Buck Hamlin or Dewey Vicknair to get the dims "dead nutz" right--but that sure is a mystery- the "beater" HE 12 I once had had both 3" chambers and the "Not Guaranteed" stamp on the flat--Now, after seeing Mr. Hughes work and expertise on this website in restoring/refinishing older fine double guns, I wish I had kept it-- I'm currently looking into a std. 2.88" chamber 10 bore Lindner Daly with 32" Krupp Flusshall tubes-- the 2.5" chambers on a heavier frame and an aprox. 11 bore shotgun- a mystery indeed.
