The lathe assembly is mounted to a flat baseboard. Visible inspection shows the headstock fitted with a model nameplate reading 'unimat 3', alongside charts illustrating drive belt placements and speed ratings. Rising directly behind the assembly is an adjustable light fixture terminating in a black dome-shaped lamp.

Arranged on the baseboard in front of the lathe is an assortment of equipment and accessories. Visible items include drive belts, high-speed steel (HSS) lathe tool bits, chuck keys, calipers, and open-ended wrenches.
