Bill,

The gun's overall finish is called "blue"...usually a rust blue (steam and chemical rusting process) or a dipped, salt blue process (a chemical immersion process with various chemicals at high temps)...depending on maker. year, model.

The "blue" you see on some of your gun's smaller parts are fire-blued...a heat treatment process which leaves a much brighter blue...

Strawed (or the golden colored) small parts are also done with a heat treament, only, process...similar to the fire-blue.
