Miller, I have a WW Greener, circa 1892 that has 13 on the receiver. Am I correct in your saying that it was not a .710 bore, as there are no other numbers there?

The right bore is .727 and the left is .728. I hope that is the case as it would make me feel better about the bores.
The chokes measure .009 in right and .034 in left.
It is kind of scary looking at the muzzle end.

The barrels measure 27 1/8" and the gun weighs 6 lbs. even.
