The immediate post-64 Winchester 94 is notorious for being made out of what some call "mystery metal." They do not take a re-blue without turning purple. Seems to me I heard somewhere that Winchester had to plate the receivers so they would take the original factory blue. The plating obviously comes off with polishing. I think a lot of things like that happened in their factory at that time. The 99Cs may have been an attempt to save some bucks, but clip fed guns were more popular (the Remington 740/742, 760 and 788, and the Winchester 88 and 100 to name a few) at that time and it may have been Savage's attempt at "keeping up with the neighbors."
