You folks are wonderful! Thank you all for sharing your expertise. I went from being very pleased to get to look this gun over closely, to now having lots of questions. Armed with even more facts, I'll get look it over again (later this week). I will share my findings with the current owner and we'll see what happens. Mr. Hoggson, that link you provided should be very helpful. I was going to pull the stock (with permission, of course) but if it doesn't have the 28 on the shell cut-off, I think I'd be very suspicious of the gun.
Ted: If I'm crossing the 'border" corridor into the Angle, I won't likely be dragging a 28-gauge M12 along. I've got a circa 1920 16 that loves the same 2 1/2-inch RSTs that my Brummy 16 shoots. Better medicine for ruffies all around.
