[J. A. EARLY]

With no dog in the fight, I do believe it may be in The Parker Story, or maybe I read it somewhere else, that all of the lower grades did have Nitre Blued triggers (and trigger guards on all grades). The Nitre Bluing wears pretty quickly, and a single trigger would get used twice as much. Thus the raw steel trigger looks like bright steel, which does look like nickel.

I nitre blue all of my triggers on lower grade guns I rework. I will look for the information. I remember reading they would also set the triggers on a red hot file pulled out of the coals and blue them that way also. I don't think I dreamed it so I will look for the info.
