When "The Motor Cycle" tested a Constellation in 1961 they summed up the test in under the following strap line "A well-mannered roadburner with tremendous punch and ultra-high cruising speeds" comparing its performance to that previously offered by a well known vee twin emanating from Stevenage. Early models employed a single Amal TT carburettor, however this was replaced by a pair of Monoblocs sharing a common float chamber with no discernible loss in performance. The Constellation, when tested, proved to be capable of covering the standing quarter mile in 15 seconds with a terminal speed of 88 mph.
This example was restored during 2009. At the time of the restoration the vendor took the opportunity to fit a pair of Amal Concentric carburettors to the head which benefitted from being flowed. The standard magneto has been replaced by an electronic ignition system combined with an electrical system that has been uprated to 12 volts. Described as running well by the vendor it is offered with a Swansea V5C and an Mot certificate valid until the 26th April 2012.
