The No. 13 Britannia (illustrated above and below) was the smallest of the company's products to combine, in the terminology of the day, the features of  "sliding, screwcutting and gap-bed". The centre height was 3 inches and the capacity between centres either 19 inches with the standard 3 ft bed, or 25 inches with the optional (1 Guinea extra) 3 ft 6 in version. A gap in the 3.5-inches wide and 2.25-inches deep bed was also on the options' list, adding another guinea (£1 : 1s) for a facility that allowed a disc of metal 10.5 inches in diameter and 2.875 inches thick to be swung within it.
The backgeared headstock carried a pulley with three grooves cut to take an ordinary "gut" or cord driving band that passed down to a 20-inch diameter flywheel with 4 grooves - so allowing a little juggling with belt lengths and alignments to produce a total of five spindle speeds.
The compound slide rest had ungraduated feed screws, but at least the top slide was marked 50 degrees either side of centre. The drive to the 7/8" diameter, 1/4-inch pitch leadscrew was through a tumble-reverse mechanism - with full set of 22 changewheels from which to built the necessary thread-cutting train. The clasp nuts were of the proper double-closure type, in gun metal , whilst the carriage was fitted with a usual-for-the-time fast-action-return by rack and pinion; there was no provision for moving the carriage steadily under hand control.
One interesting option was the 5-guinea "overhead motion", built on cast-iron uprights at the rear of the stand. An "overhead" was (and remains) a very popular fitting amongst highly-skilled turners; it allows the lathe to be converted into a miniature, precision grinding, drilling and gear-cutting machine by providing a drive to high-speed heads clamped in the position normally occupied by the toolpost; in ornamental turning the use of an overhead is essential if more advanced work is to be done. The drive to the overhead was from the flywheel, the belt passing through holes in the stand in front of and behind the headstock; a pivoting arm, tipped with a jockey pulley at one end and a weight at the other, performed the essential task of keeping the drive belt tight whilst driving the cutter, or grindstone, at high speed. The lathe was very-well presented, and sold complete on a treadle stand with a polished-wooden top and tool drawer; the weight was an appreciable 252 lbs and it cost, in basic short-bed form, 15 guineas - a guinea being a 'one pound and one shilling'.
