Another "Crap-fest".. I trust Dewey Vicknair's analysis of this FUBARed "Elsie"-- the only one of my 12 gauge doubles with smooth chamber walls is the M21 my late Father bought slightly used in 1948, and gave me in 1981-- All my pre-1913 graded Smiths show some slight chamber roughness, another reason why I clean them thoroughly after a shooting session.
I believe Dewey tends to view the Smith design as overly complicated (the HOT) and prefers NOT to take one in his shop for repairs, etc. I bought the Smiths I own (and shoot) over the past 20 years from the late Brad B-- as they were priced lower than Parkers, and especially the fine A.H. Fox guns- being a cheap SOB, that factor appealed to me- still does today. If my Father hadn't bought the M21 in 1948, and gave it to me before he and Kay moved to Florida, I would NOT own one- RWTF
