Ariel replaced the cammy 600cc Square Four with an overhead valve design displacing 997cc during 1936. The redesigned engine retained the geared twin crankshafts first seen in the overhead cam engine, although the gears had moved to the left hand side of the engine, but little else, other than the name, remained unchanged from the cammy Square Four. 1939 saw the introduction of a compensated-link, plunger equipped frame which continued in use, complimented at the front by Ariel telescopic forks, when production of the 4G Mark 1 resumed in 1946. The model continued with very little change for the next two years, until in late1948 a redesign took place, resulting in a new version equipped with an all alloy engine. The redesign was well timed as the Square Four had been putting on weight as a result of the increased specification, the alloy engine and other measures resulting in a saving of approximately 100lbs over the iron engined version.
This example of the twin pipe, alloy engined 4G MK1 has been the subject of a "painstakingly" executed restoration carried out between 2004 and 2006 that has seen it returned to a "glorious condition". The condition of the engine, cycle parts and cosmetics are described as being excellent with a good transmission and electrical system. Presented in black with no known modifications from the standard specification, it is offered with a Swansea V5C registration document and an MOT valid until the 24th May 2007.
