Refurbished Wadkin stuff that complies with current regs probably sells for more now then it was originally bought for, it's proper industrial stuff that you can use all day everyday without a problem. Think the rusty stuff without brakes etc is only really worth its scrap value.
I looked at a big old Robinson spindle moulder a couple of weeks ago, must have been 50 years old, all cast, mint condition, 3 phase complete with some cutters but none of it up to regs. They were asking £350 for it, a lot of machine for the money but nobody wanted it.
