    What makes the blueing on a Colt Python so special? It looks to me to be one of the finest bluing jobs I have ever seen. It looks like a blackish blue. How do they do the bluing on the Python? Thanks for the info. Bob[:)][8]

    The receiver will need to be polished enough to get rid of the old colors, and even that may not work on some receivers... They seem to be a PITA usually...
    Brownells will be of help-- 1-800-717-8211

    I'll be interested, too.
    I have a Browning BPCR that needs refinishing and I would like to have the receiver blued because I prefer the appearance and it will cost less.

    "I have a Browning BPCR that needs refinishing and I would like to have the receiver blued because I prefer the appearance and it will cost less."..........this should blue ok, the case color is easly removed. A lot depends on the base metal, case iron (Iver Johnson champion & post 64 Win. 94=example) dosn't blue at all (turns red or purple.

    If it is truly casehardened, and not case colored then you would have to remove the casehardened surface prior to blueing. As a side note, there is an additive that will make those old cast iron receivers black as a piece of coal....proper metal prep required, of course. Good luck

    Would that additive be sodium thiosulphate, or is that for bluing silver solder and brazing?

    XXCross, don't remember the name, just that I would get it at the local (old time) pharmacy in town that an even older smith had told me about. Probably didn't do my lungs any good either..ha!
    When Ed Brown(he gave me this tip) came out with his mag well that was soldered/welded to the frame (for the silver soldered ones), after cleaning up the joint real good, take it out of the salts and dip the soldered area only in cold water for a few seconds and then back in the salts. Do this after the rest of the metal is already blackened(10 min or so) and leave it there for another five.
    Look up "Gunsmith Kinks" vol I, there may be a reference there. Get it from Brownell,Inc.

    It's been more than a few years since I've splattered myself with hot bluing solution, but I do recall that we had an additive that was put in the bluing solution that insured that everything came out blue/black. It did a real nice job of covering the silver solder areas that we frequently had to deal with. Pretty sure it was that sodium thiosulphate stuff. As for the bluing of those damn cast 94 frames...ya gotta increase the heat of the solution.

    Had an H&R single shot cast receiver refinished a few years ago. Gunsmith said normal bluing would turn purple and not be attractive. He did some kind of fuming process that turned it black. It looks OK and it has been durable.
