The second of Velocette's M-series 'high camshaft' models, the 350cc MAC first appeared in 1934 and subsequently was bored out to create the 500cc MSS. Post-war, the M-series Velos continued much as before, with rigid frames and - initially - Webb girder forks. The MAC gained an alloy cylinder barrel and 'head for 1951, as well as Velocette's own telescopic front fork in place of the preceding Dowty, and was further updated with a swinging-arm frame in 1953. This 'barn find' MAC was purchased new in 1946 by the vendor's late father and had covered only 6,243 miles when it was laid up in 1955. Its last tax disc (expired 30th September 1955) is still in the holder fixed to the machine. The Velo has been stored in a garage for the past 56 years, its engine being run regularly up to the late 1980s; since then it has not been started, though the cylinder bore has been kept lubricated. We are advised that the machine wheels freely, the brakes work, the tyres stay inflated and the stands operate. An ideal candidate for restoration or, alternatively, mechanical re-commissioning and a wipe over with an oily rag, this delightful 'time warp' MAC comes with VOC dating certificate. Upon inspection, Rodger Franklin (Velocette Owners Club) described the MAC "as original as you can get", the only notified deviation from original specification being the silencer. A Swansea V5C document for the original registration number 'FF 6359' has been applied for.
