And how then do you pay for you're show, if not by winching out those stuck in the mud? winch cable isn't that expensive, it the Dynemma rope that is eye watering, about £2 a metre. I got my last cable from a local firm that mostly does lifts, they supplied cable fittings and all instructions.
That master looks similar to the old Bedford QL one. Pastparts rebuilt one for a friend some years back, still going strong.
