You Never Know What ....... so I'm asking.....

What does the museum staff have to say about them?

The people who were there, at the time, didn't know.

These are just too unique, to not try to model them. I might just do them in narrow gauge. The outside frame 2-6-6-2, has a Vanderbilt tender, that would look good with that style of truck, and the foundries at Sag Harbor Shipbuilding and Dry Dock Co. could easily cast the frames.
Yessss, there was a madness to my method, of making the parent company of my "home roads" a Shipyard.
