I’ve done what I could on-line researching just what Russia iron’s supposed to look like, and there doesn’t seem to be much agreement at all from the various sites.
A greenish cast, a dark black metallic look, they’re all over the place, but the general consensus now is that Russia iron didn’t have that “metal-flake blue” color like you’d see on a modern street rod.
Those on the “Model Railroader” Forum, the guys who obsess over this stuff, say the common Russia iron color on American engines was a glossy silvery-grey. The gloss would reflect the sky given the right circumstances and give the impression it was blue, especially with color photography.
It’s too bad the Erie didn’t preserve one of their K-1 Pacifics, or G-15 4-6-0’s for that matter, so we’d know for sure.
So, that silvery 0-8-0 in the picture could have had a Russia iron boiler jacket when it was originally built as a 2-8-0 in 1904 or '05 and kept it to the end, but it still strikes me as an extravagance for a freight engine. But what do I know, I’m not infallable.
I’ve tried looking up those engines and can’t find out anything about how they were finished. We really need “…someone in the know for things B&O” to sound off on this.
Anyway, according to a poster on that “M-R” topic, the National Park Service after exhaustive research says this is what a Russia iron boiler jacket should look like.
