It turns out that this gun has 2 5/8 chambers but is marked with 1 1/8 oz. proofs. Kirk Merrington thinks it Is original and non -altered.As 2 5/8 was the standard 12 gauge length in the US until 1929, does anyone know ifthe English makers bored them that way on guns ordered by Americans?

My 1928 Boss has 2 5/8" chambers.It was ordered and delivered to a guy in New York city. It is a game gun. Funny thing, previously my friend owned another Boss Pigeon gun owned by the same guy a few serial numbers before mine.

I seriously doubt that the 2 5/8" chambers had anything to do with made for America. At least as early as W W Greeners ninth edition of the gun & its development (1910) he stated that the "nominal' 2" chambered 12 gauge had chambers from 2 9/16" to 2 58" length. I do not know how much earlier this practice was used. I believe that only very early British 12 gage guns will be found with actual 2" chambers. The European standard of 65 mm s 2.559" or only .0035" shorter than 2 9/16".
  Also, 2 5/8 was an American standard, not "THE" American standard as late as 1929. Boh L C Smith & Lefever Arms Co had standardized on the 2 /4" shell in the 12 gauge long before this date, & perhaps others as well.

Go here: http://dspace.nplg.gov.ge/bitstream/1234/84152/1/James_Purdey_1930.pdfThat's a Purdey catalog from 1930. Go to 5th page -- POINTS TO CONSIDER WHEN ORDERING A GUN See 2nd paragraph, first sentence. I've seen 12g Purdeys with proofmarks for 2 5/8" chambers. OWD

Greg,
  Thanks for the link and it confirms Purdey extended the chamber length in 1930 for the American destined guns.  I wonder if Hussey would have done this practice in the early 1900s.

Yeah - that's the question.
  If they had, wouldn't they have proofed them at 2 5/8", too?
  I'm not sure.

OWD;
  You, I am certain will recall that case length was not a mark of proof for the period of time when the Hussey was built.

Nope. Forgot that. You're right, though.
  So was the "Diamond with 12-over C in it" used for both?
  "Diamond with 12-over CL" was for 2 3/4" (and 3"?), right?
