After WWII most returning G.I.s weren't think about long term collectible value and there were any number of auto shops that offered chrome plating to "dress up" that Luger someone brought home from the war. My brother has a mint condition FN Model 1910/22 from the Netherlands contract that somebody nickel plated at some point in time. I told him it looks like a presentation piece and he got it for a fraction of what the gun would have gone for with it's original finish.
In point of fact guns were well known to rust like the dickens - a blued finish isn't the high standard of durability, and plenty of soldiers had seen what became of guns with phosphate while carried thru jungles and Europe.
They cared enough to spend money out of pocket to help preserve it. A plated finish became the norm then. Nickel, chrome, whatever. It was even the standard on knives, to reduce corrosion and keep it cleaner in use. Plenty of hunting knives during that era picked up plated finishes and that trend went forward into the 1960's - which became the push to stainless steel.
And that is where our guns wound up. Plenty of cops and troopers carried slick stainless revolvers on duty, and the results were worth it, they didn't corrode or rust nearly as much.
Plated guns were just a step in that direction, the plating wasn't just for show, nor was it useless egotism. And plenty of us like shiny guns, a lot. It's not an "all tactical" or go home world. Considering the comments on black finished economy grade guns - which are universally derided.
There's no win on the internet, somebody is wrong somewhere.
