Douglas commenced post-war production in 1947 with, naturally enough, a flat twin, though unlike the vast majority of previous models the T35 mounted its engine across the frame. The former was of unit construction, while the latter displayed even greater innovation with its swinging arm rear suspension controlled by torsion bars, and leading-link Radiadraulic front fork. After development work had cured frame breakages and improved engine power, the revised version was dubbed the MkIII. The latter lasted until the advent of the new-for-1949 MkIV, which featured an un-sprung front mudguard and altered rear sub-frame with distinctive teardrop-shaped toolboxes. Standard and Sports versions were catalogued until the introduction of the MkV in 1951. Also part of the range were two specially tuned models known as the 80 Plus or 90 Plus depending on the level of performance achieved. This particular 80 Plus was rebuilt by marque specialist Roger Mortimer of the London Douglas Motor Cycle Club, having been off the road - it is understood - since the 1960s. The vendor continued the improvement process until recent times and describes the machine as in generally very good condition, with excellent cycle parts. Noteworthy features include the optional 4½-gallon fuel tank and new alloy wheel rims, tyres and tubes. Valve and cylinder head upgrades, including unleaded compatible valve seats, are the only notified deviations from factory specification. The machine is offered with SORN paperwork, expired MoT (2012) and Swansea V5C document
