Equipped with a flat and V-way bed of lighter build than the A.K.T., the competitively-priced "Leader" was a popular lathe of the 1930s and is sometimes found with marking proclaiming, amongst other things, IXL, Zyto, IXL Invicta British Made - or indeed a mixture of names cast into the bed or changewheel cover or on detachable nameplates. Despite the protestations of "British-made" it is almost certain that the bulk of the machines were made in Germany by Ehrlich and the only "British-made" part was the easily-changed casting bearing those words (remember those wallets that said, on a little tab "Real leather" ? The tab was leather but the rest plastic).
Backgeared and screwcutting with a capacity of 5" x 24",  the Leader went through several changes during its life including a completely redesigned apron with the handwheel and clasp-nut handles transposed horizontally  - and a different design of top slide; with its tumble reverse mechanism and tailstock distinctly different to other IXL models. One notable feature of the machine was the use of a tall boss to carry the top slide - probably an indication that the centre height had been extended beyond that envisaged by the original designer. The top slide swivel was marked 90 degrees either side, and cross and top slide were fitted with, for the time, generously dimensioned micrometer dials. Of a decent length, both the saddle arms were sometimes provided with T-slots making the assembly useable as a boring table.
With six threads to the inch the leadscrew was driven through a conventional tumble reverse mechanism with a spring loaded plunger for location of engagement. The tailstock, locked with a captive spanner on a simple nut, could be set over for taper turning while the headstock spindle, bored to clear 0.75", was of ground steel and ran in an adjustable tapered phosphor-bronze bearing at the chuck end - and in a parallel bearing at the other.  The spindle end thrust was taken by a ball bearing race.
Unusually for a larger lathe the backgear was operated, like a Myford 7 Series, from a lever lifting through a quadrant on the right-hand side of the headstock. The lathe was advertised as being available on either a foot-treadle or self-motorised stand - and is also shown in the photograph below..

An end view of the green IXL showing the "British Made" changewheel cover - that is, the cover was made in the UK, but the lathe in Germany. Just like, before the Trades Description Act, that leather wallet you bought with a little tag stamped "real leather" - the tag was leather, the wallet was not

A remarkably well preserved IXL from the 1930 still in the maker's paint and evidently having had only very light use. This example has a non-power cross feed apron
