Got this Model of 1905 in .38 Special, Hand-Ejector, 4th Change.
Interestingly, it's nickel, with gold-plated trigger, hammer & release button. SN 427xxx (all locations match) puts DOB at 1924.
If it's factory-plated, should the SN reflect this? If so, how?
Non-original grips and no box/papers.

No, serial number will not reflect finish.
Do you see a “B” or “N” stamped anywhere?
How about posting some pictures?

The gold plated parts lead me to believe that it was custom work outside of the factory.

Clear ,detailed pictures would take the guesswork out of it.

Without that , I'm with "VM".

If you are referring to getting a factory letter for that serial number, yes it would tell what the original factory finish was.

My bet is that is not Factory gold.
That was a very common alteration that cops did to dress up their guns. I've probably seen a thousand done.

Yes. I'm sure you're right.
As I see no "B" or "N" anyplace, nickel/gold-work must be aftermarket.
Factory letter wouldn't help my investment of $150. for the piece.
Seems 5" sq. butts are pretty common - even at this 90% NRA.
Still amazed how smooth/tight after nearly a century.
Thanks again to all.

Check the serial number that is stamped on the underside of the barrel. If there is a "B" stamped in front of the SN, the revolver left Springfield with a blue finish. A lack of the "B" indicates it originally had a nickel finish. Pictures can help to determine if the present finish is factory or not.

Right. I'd missed the "B" to extreme left of the # under barrel.
I see now plating was not an uncommon embelishment.
I assume it's done to to hide any wear, just for esthetics, or the illusion it might minimize holster-wear. Are there other reasons nickel became popular in that era?

In black powder era, nickel was much better at preventing corrosion. Nickel will not "rust" and protects the steel against the salts and sulfur residue left by shooting BP as long as it is in good condition. There is no doubt that cleaning and lubrication of guns pre-1900 was not done like or as often as today.

I am sure that some also bought nickel guns because they were bright and shiny.
