Definition of "straw"

    It's a type of metal finishing (I THINK a hardening process) which leaves the part a straw color. So, "Straw is 95%" means that 95% of the straw color remains on that part.

    Or it could be the thing in the rampant Colt mouth.

    edit Yep it's a spear. However I have heard referance to "he still has the straw in his mouth" when considering if the old Colt was reblued in the distant past and not buffed out. And I never new that corrosion paper was straw too. I agree that usually the straw referance is to part of the finish on toggle tops. Oh and nice chart. thanks


    'the thing' is a SPEAR.

    Most commonly used as far as collectors are concerned describing certain parts on Luger pistols made between 1900 and the late 30's. The various parts after manufacture are polished to a bright finish. As they are heated to harden the metal surface, color changes occur as the part cools. When the part reaches a yellow "straw" color as it's cools it is deemed the correct temper, and it's quenched in liquid which causes the "straw" color to remain.

    The first and lowest of the tempering colors.
    It's very fragile so presence and condition of these colors is a statement on little finish wear.

    Colt once used a "straw" in the barrels of their AR-15's, when shipped from the factory, it was an anti-corrosion twisted paper "straw", they discontinued it due to idiots who just loaded the gun and fired one shot......., a KABOOM was the result.

    Off topic and my apologies to the OP....

    USN_Airdale: I work in an Army Small Arms Repair Shop. The new barrels still come in that way.
