Sort of reminds me of the Edaville engine from the Fiji Islands before they added the "tender" to it. There must be hundreds of these little odd creatures all over the world. I wonder if anyone has tried to come up with an inventory of them? I'm sure many are non-operational, or in private hands, or museums, or even just junk lines. Everyone has concentrated on bigger locomotives, and these little kettles have been ignored, but I'll wager there's lots of 'em out there someplace.
