I got one of the old chain wrenches in the back of the motor still, very seldom used nowadays but handy when you need it.
Years ago I also had a mad one about 5ft long, I got it at a boot fair for a tenner, I saw one in TG Lynes subsequently for £675 or something mad like that, prob plus VAT too.
It came in very handy a few times when welding lengths of pipe in a long trench etc, you could do a weld then spin the whole lot round to do the next bit also in a nice easy downhand fashion with no crawling about. I donated it to a mate in the end when it was unlikely I'd need it again. Useful bits of kit.
