The Series 1 is the most coveted of all Jaguar E-types, and this superbly restored example benefits from a number of well-chosen upgrades. Chassis number 1E 21426 was built on 7 September 1966 as a UK-market right-hand-drive car, and dispatched later that month via Henly’s London to a dealer in Ipswich. They sold it to its first owner, a JEA Nunn, and the Jaguar was registered NPV 1. At some point, it must have found its way to the US because it was acquired there in 1981 by Dr Kurt Weiler – an internationally renowned scientist who had a long career that included stints at the National Science Foundation and the Naval Research Laboratory in Washington, DC. Dr Weiler took the E-type off the road in the mid-1990s and kept it in dry storage. After he passed away in 2016, it was bought by an enthusiast who commissioned a complete restoration by Bristol Classic and Sports Cars Ltd. This process involved stripping the car to bare metal and replacing areas such as the sills, rear wheelarches and floors before it was repainted in a striking shade of ‘Ecurie Ecosse’ blue and thoroughly rust-proofed. All mechanical components were rebuilt, including the rear axle and steering rack. The suspension gained polyurethane bushes throughout and adjustable Gaz dampers, while the rebuild of the matching-numbers engine encompassed cylinder-head work to make it compatible with unleaded petrol. A new wiring loom was installed, too. A number of upgrades were specified, such as the replacement of the original four-speed gearbox with a Tremec five-speed unit. The cooling system was also upgraded with a Revotec fan and a high-flow radiator, while a stainless-steel exhaust was fitted and the brakes were improved via four-pot calipers at the front. Inside, there is a bespoke full-leather burgundy interior, while the exterior is nicely finished off with a set of D-type-style Dunlop alloy race wheels. In total, more than £178,000 has been spent in order to bring the car up to its current standard. Having covered only a few hundred dry miles since the restoration was completed, this Series 1 Jaguar E-type is offered for sale in exceptional condition and with a complete photographic record of its rebuild.
