If you look at your site and go to the page:

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.
