I have a mill – following a number of weeks searching, viewing, missing out on good buys and avoiding the 'dogs'.
A Viceroy – apparently from a school – absolutely filthy with accumulated oil and dirt; but no rust: and, the thing that prompted me to buy it, virtually no play or backlash in any of the three axis, and a spotless unmarked bed. Oh, and the price. Probably a 1/3rd of what it is worth. 
It was set up as a horizontal, with a lot of horizontal cutters. But it also has a vertical head, a Clarkson chuck [minus drawbar] and 1/4; 1/2; 5/8 & 3/4" collets
I've cleaned the muck and crud off it and am becoming more pleased with my purchase by th minute. The 3HP inverter arrived today, so tomorrow and Friday I will be rearranging the workshop to get it set up and running beside the Bantam. I have the drawbar to make too.
Photos to follow, next week.
Then I need to learn to use it it. I have never operated a mill – though I have bought Harold Hall's book and am inwardly digesting it, with interest.
