Austin & Lagopus,
All 3 of my 2" guns have 26" barrels.
They spec out as follows:
A. Sanders, Maidstone, gun wgt. 5# 0.2 oz, bbl wgt. 2# 2.8 oz, min. wall @ end of chamber (@ start of forcing cone), Rt. .093", Lft. .088", 9" from breech, Rt. .030", Lft. 0.030".
H. Monk, Chester, gun wgt. 5# 1.7 oz, bbl wgt. 2# 3.5 oz, end of ch., Rt. .088", Lft. .090", 9" from breech, Rt. .035", Lft. .036".
W. Hodgson, Ripon, gun wgt. 5# 4.5 oz, bbl wgt. 2# 4.8 oz, end of ch., Rt..090", Lft. .092", 9" from breech, Rt. .039", Lft. .035"
These wall thicknesses were measured on a homemade device, but I believe that they are reasonably accurate.
The Sanders may (or may not) have been assembled by Skimmin & Wood, but I have reason to believe that the Monk & the Hodgson are by a different Birmingham maker.
