A few questions for the Parker experts

[Autumn Daze]

Craig, Many guns were retrofitted at the factory for the 1910 bolt plate. Yes the "WK" is the barrel stamp for Walter King. As far as chambers go I think the .798 is a starting point I have seen some variances in chamber diameters.

Refresh our memories here, Craig. Do you have your PGCA letter yet? It may mention a return to the factory between 1905 and 1910. That could explain the early bolt plate. Otherwise, I would assume that the gun was fitted with the 1905 plate while the patent was being approved.
