I've never heard either of those words. Do you mean a JCB?

[Bm] Well, JCB isn't the only firm that makes them, but yes.

Like this, sort of.

I really had no intention of selecting the correct answer. I've done this before (when the Pants site was alive) - because I'm in a significantly different time zone to most participants it makes it awkward for everyone if I take the chair.
Accordingly I invite someone else to volunteer for the position ... perhaps, as Tuj got us on the right track (sorry) and Chalky the wheels/track, one of them might care to break the champagne and launch the next subject? Please!

Thanks Duj. Nice thought, but I don't feel I made a significant contribution. Perhaps Tuj would like a crack at the next one? If not - perhaps someone else is burning for a turn?
