    Lets Talk Ejector Springs

    Kuhnhausen says 1st, 2nd, 3rd g. springs are interchangeable and also that 1st g. were brass plated. I checked my 3 1st g. SAA and 2 were in fact brass. I've never heard any mention when discussing 1st g. originality that the spring was brass. Is this a minor issue that no one cares about? Were all 1st (1873-1956) brass? Are there any differances between 2nd and 3rd g. spring? THANKS

    1. Can be an issue; only on the purest of the pure collectible Colts for originality, would it make a difference IMO.

    2. Yes my 1st gens are brass, but it's unclear to me if they all were brass. 2nd and 3rd gens are not brass.

    3. Yes, 2nds appear to be carbon steel. 3rds must be stainless steel, they won't take bluing.

    When the spring is compressed and it tries to form a figure S instead of staying straight, it's worn on the sides unevenly from rubbing on the inside of the housing. Notice some coils will be flattened. Time to change for me, but if they're still work properly, just keep them clean and oiled to mitigate further wear.

    Im happy someone else on the planet, has finally asked the question.
    I have been asking this question for years to various colt collectors, and i just get a (dame never been asked that,or even thought about it till now).
    A friend has quiet a number of rimfire sa's so he went home and checked them out.yep 8 out of 10 were brass.
    All my first gen saa'a are brass and one is plated.
    All of my near mint lightnings are brass, not plated.
    SO let the experts settle this.
    Date range, brass and or plated and why.
    I would so much like to put this subject to bed once and for all.

    Kuhnhausen says brass plated. But like I said 2/3 of mine were brass not brass plated. I found 2 old used brass springs in parts bin and replaced the one that was not brass to keep it original. So, I'm understanding:

    1st- brass or brass plated
    2nd-carbon steel
    3rd- stainless steel.
    Is this correct?

    I did a little research on the ejector springs. First made from a metal called "sterling metal" and was doubtful that it contained any silver. These were used on the early Peacemakers and all Cavalry models.
    Brown Brothers of Waterbury, Conn. made the springs for Colt but how long they were used is unknown before switching to the regular steel springs. Could the sterling metal be the ones that look like brass?

    Allow me to clarify this issue. "Sterling metal" was an early version of phosphor bronze, containing more tin than copper, hence a more "silvery" color. It has been used for decades as spring wire. It looks like brass to the layman but brass is not fine grained enough to produce a good spring, and would easily oxidize and break. The inside of most original springs shows the true color of the sterling metal, while the exterior will oxidize with a thin, dark patina. Modern Colts are using steel springs due to ease of manufacturing, strength and lower cost.

    The sterling metal was only used for the very early Peacemakers. American Sterling Company was in business 1871-1880.
