A development of the Major the Senior "V.S." used a wider main column, a stiffer, more robust dovetail-type overarm in place of the round bar and had a vertical knee travel some 1.5" greater.
When it was introduced in the early 1950s, the machine's dovetail overarm was recessed into the top of the main column - which allowed the motor to be left in place on top of the machine - whilst later models were redesigned to allow the overarm to sit on top of the column. Even so, whilst the vertical travel remained unchanged the motor had to be shifted to a less convenient position on a hinged plate within the cabinet base.
With a working surface of 31" x 6.5" the table had with a longitudinal travel of 22", a cross travel of 7" and a vertical travel of 13.5". The table was driven through a 3-speed gearbox powered, as on other Senior millers, by a simple but efficient V belt take-off from the main motor. The maximum distance from the spindle nose to the table was 13.5". Twelve spindle speed were provided of: 60, 86, 104, 136, 169, 267, 329, 537, 642, 845, 1050, and 1660 r.p.m from a 2 hp 3-phase motor - the slower six speeds being driven through a lathe-like "backgear" assembly built into the main column. A full electrical system was fitted, with overload and no-volt release, together with a mechanically driven suds pump. A "Universal" model - with swing table - was also produced in both Mk. 1 and Mk. 2 versions and these are illustrated below. All accessories designed for the M1 and Major also fitted the "V.S.".
