16 Gauge "PH" question

[Edward Hamm]

This is only my second day here...how do I find out about the "Serialization Book"? In fact, what is it? Lot to learn here, but it is very interesting!

[Steve Hodges]

Ed, give us the serial # and we can check the book

[Edward Hamm]

Sure...and thanks. Serial #: 203536.

I believe Dean is correct. The gun was most likely a late Twist barreled gun that was refitted with Vulcan barrels. Also if the gun was a factory fluid steel gun the rib inscription would read "Parker Steel" "Parker Special Steel" was reserved for G grade guns.
