Very cool, Rooster. And that reminds me of the boilers I’d like to model at some point. Here’s a photo of the boiler room of a large Comstock mine: the East Yellow Jacket.
A couple weeks ago I poked around and found where the boilers came from, the Union Iron Works of 'Frisco. Here’s the catalog pages.
The Carrick boilers would have been from a different maker of course, but the configuration of 2 long boilers and a lateral accumulation tank above is very similar.
