[C.O.B.]

Just for grins I checked the weights of 5 16's four are 0 frame and one is a one frame all with 28 inch Damascuss, Twist or Bernard barrels and the largest gap in weight was only 3 oz.
A GHE 0 frame 3.6lbs, GH 0 frame 3.8 lbs, GH 0 frame 3.6 lbs Lifter 0 frame 3.6 lbs. The surprise is a CHE one frame Bernard which was the lightest at 3.5 lbs.
