Identify boiler

maybe look under the upper cover, where the electrical box is screwed on

Looks like a Utica PEG

My guess is it's a Dunkirk PSB-4D. 112K input

When I see blue, I think Burnham. But we don’t see many Dunkirk’s out west here.

…..as is Crown, but I think you once mentioned that they are a rebranded Dunkirk.

Dunkirk and Utica are the same thing I think.

There have been a lot of blue boilers over the years, I think H.B. Smith had blue for a while as did all the above mentioned.

It's rare to see a boiler without at least the ASME plate riveted on.

Wana bet it's behind the 1900 Box?
