Walt, I wish I had your book---I wouldn't be pestering all with these questions. BTW, the chokes are 2 and 4 and measure M/F, 26" barrels stamped on the bottom LLH (I know what that means). I did fail to mention that the top of the frame is stippled, and the same border appears on the triggerguard in a rectangle, and appears as a border on the tang.
So, it's a Field Skeet?
