That is an interesting find, having a soft spot for Shay locos I have this from Practical Machinist bookmarked re T-style boilers:

Sorry for taking so long, I was out of town for a week. Thank you for including that information
on the "T" boiler. Those would be nice with the tubes in them. My toy doesn't have them. It's just
a big area and no place for a fire box. I could fill it with water and place it in campfire.
