First produced during 1922, the second most common Dalton, the Lot 5, could be had with either a 30 or 36-inch bed. The lathe (it was an unfortunate, rather ugly-looking design) shared many components with the Lot 4, though with a much-improved specification including independent power longitudinal feed by a separate feed rod that drove, via a key, worm-and-wheel gearing inside the apron (though no small Dalton ever had power cross feed). Some very early Lot 5 lathes (probably fewer than 100 and as shown below) had components including the leadscrew (a standard 3/4" x 12 t.p.i as used on all Daltons) power-feed rod and bed, though all were smaller and more lightly built and the bed had its feet cast in. This rarer type also incorporated a most useful automatic disengage for the power sliding feed, exactly like the contemporary and competing Flather 7-inch. Three examples have been examined, Serial Numbers 32, 36 and 62: all appear identical and are fitted with a single-piece changewheel guard as used on the Lot 4 machines instead of the two-piece assembly found on the later Lot 5 types..
