Thanks to a very gracious and savvy P.G.C.A member with the proper equipment, I now have some accurate figures which to work!
According to this fine gentleman, the chamber runs .770 out to .761. Then the barrels are as follows:
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)
