Upon fireing a Theur cartridge, the heat resulting from the combustion of the gunpowder was concentrated in the cylinder body. Because the thickness and density of the metal in that location, the heat lasted longer there than at the Theur breech mechanism. This heat, plus routine cleaning is what destroyed the blueing on the cylinder.
Then, how would you explain that the bluing on the cylinders of modern repro Colt revolvers disappears after fireing no more that 2 or 3 rounds from each cylinder... even if you do not clean the cylinder after fireing?Heat from a Revolver being fired, will have no effect on the Blueing.
Acids or strong enough Alkali can degrade or remove Blueing but Heat associated with firing a Hand Gun, no.
The Wood Stocks would be combusting way prior to there being enough Heat to damage the Blueing.
I do not know...Then, how would you explain that the bluing on the cylinders of modern repro Colt revolvers disappears after fireing no more that 2 or 3 rounds from each cylinder... even if you do not clean the cylinder after fireing?
Heat from the Revolver being fired...should not effect the Blueing then.I do not know what type of steel was used in 2nd or 3rd generation Colt cylinders, but they were supplied in the rough, un-ingraved by Uberti. After machining and roll engraving, the blueing was done using the original Colt factory process of burying the metal parts in bone charcoal and heating in a kiln/oven at high temps for a period of time.
I'm inclined to question the premise that they were left unfinished. Where did that info come from? I had a Dragoon with some original finish on it and its cylinder looked like the rest of the gun, no sign of 'in the white'. Also there are several high condition Dragoons in exhibits & collections & I never saw an unfinished cylinder.Why were their ncylinders left unfinished (blued)?Was there a practical reason?
I thought this was the case hardening process? I have seen a formula - supposedly the Colt original - for blueing which used a liquid.the blueing was done using the original Colt factory process of burying the metal parts in bone charcoal and heating in a kiln/oven at high temps for a period of time.
I have seen it mentioned several times while searching info on the walker. Also mentioned in the 9th edition of Flayderman's Guide page 83, Colt Walker Model Revolver......."cylinder in the white".I'm inclined to question the premise that they were left unfinished.

Fine. The revolver retains 40% of the original blue and shows only limited firing wear.

The action is crisp and functions perfectly. This is a fine example of an original, first contract First Model Dragoon revolver with "U.S. DRAGOONS" marked cylinder.
