The Austin-Healey 100 was revamped for 1956, BMC's 2.6-litre C-series six replacing the original four-cylinder Austin Atlantic engine, while at the same time the wheelbase was lengthened slightly to enable the inclusion of two occasional seats in the rear of the BN4 version. In 100/6 tune the pushrod six produced 102bhp - 12bhp more than its predecessor - though the inevitable weight gain meant that there was little if any improvement in performance. Although stylistically similar to the 100, the 100/6 was easily distinguishable by its 'crinkle' radiator grille and bonnet-top air intake. In 1957 an improved 'six-port' engine became available, and this 117bhp unit was fitted to all the newly introduced BN6 two-seater roadsters. Top speed improved to 111mph with 1.7 seconds cut from the 0-60mph time. This BN6 two-seater was imported from Arkansas, USA in 1990 and then converted to right-hand drive. Its first owner in the UK was a Mr Brian O'Connell (see purchase invoice on file). The current vendor purchased the car in 2001 and carried out a full restoration to a very high standard during 2004/2005. This 'last nut and bolt' restoration included an engine rebuild (cylinders re-bored, crankshaft re-ground, new pistons, crankshaft and flywheel balanced, pro/race damper fitted, etc); oil cooler fitted; disc brakes serviced; brake servo fitted; gearbox overhauled and overdrive fitted together with a new clutch; new all leather upholstery; new high grade bespoke carpets; bespoke mohair hood and tonneau cover; four new 60-spoke chromed wire wheels; and a stainless steel exhaust. Since completion 'CSK 856' has won the Austin-Healey (New Forest Centre) concours but has seen relatively little use - high days and holidays, mainly in the dry - as it is the vendor's second Healey. The car comes with State of Arkansas Certificate of Title, sundry (previous owner) invoices and expired MoTs, and all the MoT certificates and tax discs relating to the current ownership. We are advised that they show the continuation of mileage but because of a malfunctioning odometer during the previous and (early) current ownership, the apparent mileage was greater than the actual total covered. This problem was rectified during restoration when the speedometer was re-calibrated to take account of the overdrive unit. The car is offered with the aforementioned documentation, Heritage Trust Certificate, sundry restoration invoices, current MoT/tax and Swansea V5. The Austin Healey Club estimates that there are approximately 120 BN6 two-seater variants remaining, making this model quite rare.
