Hi Buck,
I’ve watched this one on Kirby’s website and wondered when it would get picked up. Nice score!
I’ll be waiting to see what you find out from J.P. Daeschler as to its details.

A curiosity point: As it is “in the white” and not engraved/finished hence no color case hardening, do you suppose the surfaces are more prone to wear if it is shot very much?

.360 2 1/4” is a compelling little cartridge.
