Based on the knee and table of the "Junior" miller (though without the horizontal faculty and less the speed-reducing backgears) the "Light Vertical" had a non-power feed table of 25" x 6.5" and later 28" x 6.5" - though these figures are not fixed and other tables sizes, a little shorter and longer have been found.. The great advantage of this model was it's turret-miller-like-capability - a horizontal bar allowing the head to be moved in and out and also tilted through 90 degrees either side of vertical. The bar was held in two housings that, on early machines were bolted to the top of the main casting whilst later ones were of improved rigidity and cast in as part of the main column.
Expensive when new, this very desirable (and rare) miller was superbly made and finished and used the S-Type vertical head with a Timken taper roller bearings and a No. 2 Morse taper spindle. Five (later six) speeds were available from 50 to 3000 rpm and the head was fitted with both a worm-driven fine-downfeed control and a rack-and-pinion rapid-action drilling quill. On some versions the head was inclined by a convenient and easy-to-operate  handwheel-driven worm & wheel mechanism..
