I was lucky enough (I hope
) to pick up a set of 20 gauge 0 frame D2 28" extractor barrels online, After fierce competition from a scion of a well known Idaho family of deep pocketed Parker enthusiasts, I came away with the barrels holding the serial # 99694 at 1/2 of my max bid. I expect they will find their way on to one of my 0 frame 16 ga hammerguns. While there are more GH D2 20ga guns than are listed in TPS, there aren't all that many about and even fewer spare barrels...luckily, Russell has the Parker hammerless to hammer conversion down pat...he even order a set of the Galazan barrels for a DHE 20g of his...we'll see how they work out too...
