Douglas announced their new horizontally opposed across the frame twin during September 1945 with production of the new model, typed the T35 Mk I commencing in 1947. The new model was notable not only for the engine configuration but also the rolling chassis which featured a pivoted fork rear frame sprung with torsion bars and leading link forks, typed "Radiadraulic" by Douglas, with compression springs and hydraulic damping.
A revised model, benefiting from improved cylinder heads developed by Freddie Dixon was introduced during 1948, typed the Mk III, followed by the Mk IV in 1950 with a revised rear sub-frame and new toolboxes and the Mk V, as offered here in 1951, which featured a revised front mudguard and mounting.

This example dating from 1952 is described by the vendor as being in good condition in all respects. The engine benefited from a rebore and new pistons shortly before the machine was acquired by the current owner and it retains its original registration number.
