Some catalogs refer to the EH/GH as one or the other, but not consistently. In my experience, the NH/PH situation is different. Very few large frame grade 1 guns were marked as a P grade in the early days. They seemed to be reliably stamped with the NH marking. The confusion about the markings on the gun are probably a result of the marking being applied before the barrel selection was made. Another odd situation is that the eight gauge was not described as an EH or an NH, only the ten.
