Bill do you think this rib was installed at the parker factory, "Maybe late" ???
As you can see their are no date codes on the barrel???
I did no work on the top of the dolls head…
Brownells chamber gauge in the barrel indicates 2 7/8" chamber
I shoot only 2 3/4" shells in the gun.
SERIAL NUMBER 32 inch vent rib barrels
