Just meant the internal parts not the frame etc. That will get blued. I bought a mdl 10 on gunbroker that is pretty ratty. At least according to the pictures
I needed a mud season project. It has bluing wear and some pitting. I'm going to just see what I can do about cleaning it up a bit and then slow rust bluing it. I did a rifle that way once and it turned out pretty well. I'll keep yall posted.
No matter how bad the trigger and hammer look, I suggest you leave them alone. Just clean them up with some strong solvent. As I said earlier, the hammer and trigger on your Model 10 are Case Hardened. This means they have been hardened to prevent wear, and the colors are a result of that process. At one point S&W actually trade marked the Case Hardening on their hammers and triggers to keep cheap foreign knock offs out of the country.
This is a photo of the rear of the hammer on an old S&W 38 Military and Police (the forerunner of your Model 10). The REG.U.S.PAT.OFF. marking can be clearly seen. S&W stopped marking hammers and triggers this way a long time ago, don't bother looking for it on your Model 10.
I have lots of S&W revolvers, much older than your Model 10. Some of them have a lot a lot of wear to the blue. This is one of my favorites, a 38 M&P round butt that left the factory in 1939. Lots of wear to the blue on the side plate. I would not dream of refinishing it, I like it just as it is.
Very generally speaking, refinishing a firearm will decrease its collector value, unless the old finish was seriously rusted and pitted. Then a refinish can enhance the value, over its value in the deteriorated condition. This 44 Double Action left the factory in 1881. At some point it was refinished. The trigger and hammer were blued, a dead giveaway that it had been refinished. It was a pretty poor refinish job, the edge of the side plate was rounded over and sticks out like a sore thumb. Because of all this, I got it for much less than one in pristine condition. By the way, DO NOT polish the side plate of your Model 10 separately from the frame. Inevitably that will lead to rounding over of the edges of the side plate, like this. The joint between the frame and the side plate should be almost invisible. If you are going to do any polishing, polish the frame with the side plate installed to avoid rounding over the edges of the side plate.
Ultimately, the decision is up to you. It is of course your gun and you can do with it as you wish. You may not be interested in the collector value of your model 10, there were a bazillion of them made. But unless you do a non-detectable refinish on it, you will reduce its value.
