I think its a unique contraption whatever moniker if applied to it and the idea was to paint a picture of just how unique it was regardless of technical jargon which in my mind is secondary to machine itself. Call it what you like..at least it wasn't labelled as a dishwasher.
Hmmmm... What it did remind me of was Steam Punk..put some rubber tires on it shrink it down and it would make a bizarre steam powered snow blower for a driveway..
So..what is the correct technical term?? It seems like I got into some hot water from Hot Water..Maybe I should have used the title "Name This Machine"..Regardless.. one in G scale would be great for the garden railroad, but Id rather be by the fireplace.
