Details:
This is a pair of crossed slideways (ie two individual slides bolted one on top of another) by 'Unislide' - a UK manufacturer of precision slideways.
Each one has a working surface of 4 x 6" (yes, they're imperial sized) with a range of movement of 2" and are fitted with extremely fine leadscrews - 1/2 mm pitch!
These are, normally, used in scientific research laboratories for precisely moving optics and similar things - but could, equally, be used as the stage for a miniature, precision, jig-borer - the uses are only limited by your imagination!
They're made from aluminium, so, probably, aren't suitable for milling.
