 Has anyone built any of these? Does anyone have any extra copies?

One day I might have a go at said robotic dog - assuming I can find 
enough DF92s, etc. Doing it in transistors wouldn't be the same :-)

 Any kind of description would be appreciated! What did it do? How many
tubes/valves, etc.?
I looked up the U.S. equivalent tube for the DF92 valve and found the 
1L4. A similar one, much more common is a 1U4, used in many portable radios
before transistors. All battery filament (1.4 volts, 50mA) miniature pentodes.
