Coles Mobile Crane
This is a copy of the Coles Mobile Crane, Dinky Supertoy № 571.
I have used black and yellow or gold parts where I have them, to follow the colour scheme of the original as much as I can. Also, the model is hand-operated by two crank handles protruding from the sides of the body, just like the toy.
I have however made two changes. The hook has a pulley and a return cord, rather than dangling from a single thread, and the jib is raised and lowered by a heavy-duty threaded rod; the forces involved were much too high to do otherwise.
