A works publicity picture of the Mk. 1a cast-iron DB200
This had many features to distinguish it from later versions including a 12
3/8-inch long base casting  and only 51/2 inches between centres. Although not clear from this picture, there are no V-grooves for the bed bars, instead holes were bored in the end of the casting and the bars retained by horizontal grub screws, one at each end.. The 35-mm-diameter handwheels were the second type to be employed and had a straight knurling around the edge (others have been found of 28-mm diameter, slightly thicker and with a diamond knurl pattern)

Rare and now highly-prized, this Emco Unimat is of the very first type, and almost certainly manufactured in 1954. Identification points include: crackle-black paint finish; short bed with the rails fitting into holes at the tailstock end; a nut holding the tailstock barrel in place; one-piece tailstock with a marked cantilever to the rear; no carriage lock and narrow drive pulleys with the largest diameter on the spindle to the inside  - though the pulley on the motor in the example above may be non-original. This example, unlike others seen, has  flat tops to the front and rear walls of the cross slide casting and a crudely-finished radius where the top and front faces of the headstock meet.

Another early example, this time with a wider radius between headstock top and front sloping face. The alignment bar between headstock and base was engineered by a previous owner

An unusual arrangement of the gear on the very short spindle drive handle. Later types had continuous teeth

The comparative roughness of the castings on very early models can be gauged from this picture of the one-piece tailstock (the lower Allen bolt clamps the unit to the bed rails). Note the absence of a locking bolt at the back of the carriage

A clear picture of not only the badge but also the texture of the crackle-black paint finish

The distinctive nut retaining the tailstock barrel was only fitted to very early production examples

Cross slide front flange without an oil hole to lubricate the feed screw

Wire drive belts. A guaranteed method of wearing out aluminium pulleys

From day one fastening were simple with commercial Allen socket screws to close down adjustable units and simple slot-headed screws to lock the bed and cross-slide bars in place.
