Unfortunately I disassembled the thing before I discovered this news group, so I
cannot take more pictures. I am working on a similar machine and will be sure
to get pictures of the internals..
As for how many pieces are in it I do not know. It stood nearly 4 foot tall.
The back half of the machine room, the lower part behind the red tower is
completely solid, it is not hollow. That part really used a lot of bricks. I
would estimate 10-20,000 pieces but I do not know. . . it wieghed about 20 lbs
without ballast.
Thanks for your feedback!
