If you look at your site and go to the page: http://www.inficad.com/~tvj/jeffbots/stoomdorm.html you talked of another one of these Tomy's being in existence. I used to have one of them, and it had the same type of structure on the top with a more rounded resevoir for pneumatics and the same pump system. But instead of the scissors on the bottom it had feet, I believe they were like triangular wheels that would make it move in a walk/hobble type of manner across the surface (never did work very well, but then again I was younger then and probably didn't pay much attention to it, and I probably destroyed it in some manner)... :-) now going to college for mechanical engineering I seem to pay attention ALOT more to those things. Great site by the way. I started a little collection of my own, but I think I will just use your website of a checklist of all thats out there. And if someday I happen to be cleaning out my cellar and it just so happens to be down there, I'll send you up another email and pics. Keep up the great work. ~James
