The Leinen was available in an almost bewildering variety of special forms for production work - and, in addition to the machines illustrated in the ordinary catalogue, many special-purpose units were also constructed either as one-offs, or in small batches to special order. A huge number of accessories were also listed for these lathes some of which, together with those for the precision plain-turning models, are illustrated on pages beginning here.

Type L4 RS EP. A production lathe equipped with (like the LZ screwcutting version) a single-pulley drive to the backgeared headstock from a two-speed clutched gearbox which gave ratios of 1 : 1 and 8 : 1. When used with the standard-fit 3-speed, three-phase motor twelve speeds were provided from either 13 to 1567 rev/min or 13 to 3135 revs/min The lathe was supplied fitted with a quick-action collet chuck, a Type w-31-st lever-operated compound slide rest and a Type r-3-a capstan-handle quick-action drilling tailstock.

Type R1 26 Precision Turret Lathe. This model was designed for the mass production of smaller components. The motor-drive system was different to other models based on the LZ screwcutting  version, having a  3-step headstock pulley,  single-speed motor, two-speed clutched gear change and backgear to give 12 speeds in the range 56 to 2240 rpm. A foot pedal reversed the direction of rotation.

Type ER 8T Precision Capstan Lathe.
The 2-speed motor drove via a two-step V pulley to provide two ranges of 4 speeds spanning 247 to 4900 rpm.
The lathe incorporated an automatic stock feed and a reversing reduction drive for thread cutting.
Another version, the ER6, was advertised as the "
Instrument maker's high-precision hand-screw and second operation small turret lathe".

Type J-26-HR and (below) LHR Second Operation Lathes.
These models were equipped with a quick-acting collet chuck and could be supplied, at extra cost, with either a simple foot-operated mechanical brake or an electro-mechanical laminated clutch - both of which stopped the spindle almost instantaneously.
