Ken, the builder, is a retired container-crane operator, and has a lifeling interest in, uh, cranes. In fact, he luffs them to bits [that’s a pun, BTW, if it’s too early in the morning for some of you].
It does everything that the real thing does, but is not, he spoges ruefully, actually steam-driven.
There is more if anybody wants me to post it on YT.
