I read that, too, but they didn't SHOW one. I figure it is kind of like the high polish S&W "Victory Model" .38s. Yes there is such a thing. Six of them; SN 1000000,I read an old post on a different board that said they didnt make them in chrome, but then corrected themselves and said they did however make several for high ranking officers.
SNs V 1 through V 5. Chance of Grandpa's Surplus Gun being factory nickel (they didn't chrome plate in those days) is approximately zip point nil.
But if you showed close clear pictures, you could get expert opinions.
