Thanks, Dave for this valuable information. So the figures Mr. J. arrived at are within the tolerances for a 12b identification on the gun?
(.765-.770 Parker Story)
(.770-.761 Measured readings)
And one final rookie question--Would the 30 1/4" barrels have been something pretty commonly found on the 12b gun?
