Manufactured by P.K. Douglas Pty Ltd in Enfield (a suburb of Sydney), New South Wales, Australia, the Douglas "11-inch" shaper would have been made during the 1950s and 1960s. Of apparently original design the machine had a 360-degree swivelling box table with a length, width and height of 10", 7" and 8" respectively and travel of 11 inches horizontally and 10 inches vertically. The table power-feed rate varied from 0.005" to 0.03" per cut. The table box had 3 T-slots on top and two on each of the front and one side face. A double-bracket support arm, bolted to the front edge of the cast-iron chip tray, was arranged so that, even when table was tilted, it offered full support for the entire length of travel.
A 3/4 h.p. motor bolted to the back of the machine drove forwards through a 3-step V-pulley (and optional clutch) to give ram strokes of 42, 62 and 88 per minute. Both the crank and large bull gear  were supported in ball races and the arm could be adjusted to vary the stroke which was, as usual, arranged to be faster on the return than when cutting. The tool head, which could be swivelled 60 degrees either side of central, had a travel of 3 inches and the clapper box could accept cutting tools up to 5/8" square.
A 5-inch capacity, robustly constructed swivelling-base machine vice was fitted as standard as was the electric motor and table support bracket.
