The "more advanced" I was referring to are the pistons, and gears, and
motors. I am going to London in a few days, can it be picked up there?
Say at like Harrods or the like?

Best to try and go just outside of the centre, to say Brent Cross, where you can find it for (...) (28 years ago, 15-Dec-98, to lugnet.robotics)
