RIGHT--.730 to .731 at the end.
LEFT--.731 out to .732. at the end
Choke (?)- cyl & cyl
Chamber--2.425 (2.5)
So what does all this mean? Darned if I know. What I DO know is that it sounds too big to be 14 or 13 gauge--shucks!!! Sounds like many of you mentioned--some version of a 12 ga. --most likely a 12b???
Anyway , a BIG THANKS AGAIN TO ALL WHO HELPED ME!!!
P.S.--Even though it was probably luck, I'm pretty proud of my" homemade barrel measuring device" With it we came up with a figure of .724 compared to actual values of .730-.732 for a difference of only six to eight thousandths. Not too shabby for a magic marker tube, a little fine sandpaper, and a ramrod! (plus someone else's caliper)

"The Parker Story" states in Vol II, page 524, first column, that a 12b brass shell measures 0.765" at it's base. This is exactly five thousanths less than the chamber opening of 0.770. The small difference is for fit, to insert and remove the shell. The bore sizes are 12ga.
