Armour Alloy II is a blue barrel or frame that was given .002 nickel plating before Stainless Steel.The platter's could not keep the coloring the same . T/C had too many returns because frame and barrel did not match in color. T/C discontinued the Armour Alloy II series. The following barrels were made in both 10" & 14":22 LR,223 Rem, 7 TCU 7mm Super Mag,30/30 win, 357 magnum (no 14" 357 mag),357 max (no 14"),44 mag,45/410 VR & choke (no 14"). They made a lot of 7 TCU 14" in AA. I looked for the years and could not find it now. I have it some place. I hope this will answer some of your question. I copied this information from other good people that give it on some of the lists and Webb sites thur out the years.
Good shooting, Twyman
