Make sure you get collets for it, because the 5v seem to be the sort you only find in the bottom of a box of hens teeth at the end of a midnight rainbow
Well thanks for all your replies and apologies for wasting your time. Had a (mechanical) breakdown in the morning coupled with flood diversions meant I got there bang on the time the auction office said they'd start selling those lots rather than the 1/2 hr early I was hoping.
It'd already sold. Perhaps the rain sold things quicker than expected. But maybe wasn't a great loss, no sign of tooling or the big vice that was once in place.
