My S&W New Model Number Three left the factory in 1882 with a nickel plated finish. Then in 1965 it was sent back to the factory and was refinished. In fact the entire gun was gone over with a fine tooth comb and now over 45 years later it still locks up as tight as when it first left the factory. So while I did not have the gun refinished myself, a previous owner did, and S&W did a beautiful job.
(1) I think it looks pretty cool
Yes, a nickle plated gun looks pretty cool.
(2) It is supposed to be more resistant to the the effects of BP
Back in the 19th Century, the blue finish applied to firearms was not as robust as the blue used today. So many guns were given a nickel plated finish as an alternative to blue. In fact, with some models produced by S&W they actually shipped more guns with a nickel plate finish than a blue finish. This was particularly true of some of their pocket pistols. But today's blue is far more robust than the 19th Century blues, and it will stand up just fine to the effects of corrosion. It has already been explained that Black Powder is not as corrosive as many think, so I won't belabor that thought. Suffice it to say, modern blue stands up just fine to Black Powder fouling. Most of my cowboy guns are blue, and I shoot them with Black Powder all the time.
(3) I have heard it is easier to clean
You have heard wrong. This is the same misconception that a lot of shooters have about Stainless being easier to clean than a blued finish. The actual process used to finish the gun, whether it is blued, nickel plated, or Stainless, has nothing to do with how hard it is to clean Black Powder fouling off. What matters is how polished the metal is. If there is any roughness, that gives the fouling something to cling to, and makes it more difficult to get the fouling off. I have shot Black Powder through many blued guns, nickle plated guns, and Stainless guns over the years, and I am hear to tell you that as long as the surface polish is the same, it takes the exact same amount of elbow grease to clean the fouling off.
I do agree that the bright finish of a nickel or Stainless gun will highlight residual fouling that a blued finish might hide. But the blued finish is no more difficult to clean.
(4) I think it looks pretty cool... Grin
I will certainly agree with you there.
As for the cylinder face flaking from constant BP use, why would Black Powder cause that to happen more than Smokeless? The forces involved when a Smokeless round is fired are more violent than Black Powder. If anything, nickel should start flaking off with the more violent effects of Smokeless. The other thing to consider of course is the layer of copper underneath the nickle. Traditionally, steel was always copper plated first because copper adheres better to steel than nickel does. Then the nickel was plated on over the copper. The thing to be aware of with nickel plating is that ammonia will attack copper. So never use a powder solvent that has ammonia in it with a nickel plated gun. The ammonia can seep through minute holes in the plating and then go to work on the underlying copper plate. Given time, the ammonia will degrade the bond of the copper to the steel, and that can cause both the copper and the nickel to flake off. I don't know anything about nickel plating without a copper flash underneath.
In any case, I do not shoot my New Model Number Three at every match, but when I do I make sure to clean it the same day (which is more than I do with my Colts). So far, so good.
I am no expert on nickel plating, but Electroless Nickel plating is plating done without the aide of electricity, hence the name. Electroplating is done by submerging the parts in a bath that conducts electricity. A piece of nickel is connected to one of the wires, I forget which one, the other wire is attached to the parts to be plated. I think. The electric current strips off molecules of nickel (or copper, or whatever you are trying to plate) from the piece of nickel and deposits them on the part being plated.
No electricity is used in Electroless Nickel.
http://en.wikipedia.org/wiki/Electroless_nickel_platingFor what it's worth, I worked in the electronics industry for a long time, and we plated a lot of parts. I think I remember that the Electroless Nickel was not as durable as Electroplated Nickel. It's cheaper, that's why it is done.
Anyway, the final finish of any plating is strongly influenced by the underlying surface of the part. If the part is highly polished, so will the plating be. If the part has a matte finish, so will the plating. I suspect the reason the Electroless plating came out highly polished was because your friends polished the dickens out of it.
