now the plot thickens. let us say the poster's fox receiver is made of the post 1912 chrome-vanadium-nickel alloy steel that fox called chromox. how does he or anyone else who annealed it, get it reheattreated by quenching? forget about the case hardening. temp and time parameters? what is the rockwell target? have any of you men who had fox receivers redone by noted restorers, ever been told how hard your receiver is on the standing breeches, water table etc?
