Last Dollar,
The frame is 1.945" tall right at the barrel juncture. 1.990" wide with a taper starting right at barrel juncture on side to about 1.9 at stock.
Don,
barrels have no serial numbers. I suspect it a composed set, as the rollmarks on left barrel of each is slightly different. The M/F set has a 2 stamped on the left lug and sports a mid bead.
Recoil Rob,
The frame is hogged out pretty well in the center, leaving the side of the frame only about .08". Any sculpting would have to be right at the pin.
