- Distinguishing features
- The three factory-entered 1953 works C-Types built for that year's Le Mans 24 Hours: Dunlop disc brakes (the first Le Mans win on discs), triple Weber 40 DCO3 carburettors in place of the customer cars' twin SU set-up, a lighter aluminium body with revised aerodynamics, works-tuned XK twin-cam producing approximately 220 bhp, and works-specification suspension and cooling. XKC 051 (Rolt / Hamilton) won Le Mans 1953 outright; XKC 053 (Moss / Walker) finished 2nd; the third works car finished 4th. All three sit within the standard XKC 001 – XKC 053 chassis sequence.
- Value premium
- Effectively an eight-figure premium over a documented customer C-Type in equivalent condition. The public reference is XKC 052 (Ecurie Ecosse, ex-1953 works Le Mans entry) at $13.2m, RM Sotheby's Monterey 2015 — no subsequent public sale has displaced it. Any hypothetical current sale of a 1953 works chassis with Le Mans podium history would be negotiated privately rather than at open auction.
- Inspection points
- Confirm chassis identity against the Jaguar Heritage Trust (JDHT) archive and the international C-Type register; verify the Dunlop disc brake system is period-original (calipers, discs, master cylinder) rather than a later fitment; verify the triple Weber 40 DCO3 induction is period-correct and matched to the works engine specification; check the aluminium body for post-period re-shelling and the spaceframe tub for later welding at the node joints. Continuous documented ownership from period, plus period photography from the 1953 Le Mans entry, are essential supporting evidence.
- Authentication
- Only three 1953 works cars exist and each is individually known and registered with Jaguar Heritage. A car claiming 1953 works / Le Mans specification is either one of the three documented chassis (XKC 051, XKC 052, XKC 053 — the three cars Jaguar entered at Le Mans 1953) or it is a customer C-Type upgraded to works specification post-period, in which case it must be priced as a customer car with modifications rather than as a works car. Demand a JDHT certificate that names the car in the 1953 Le Mans works entry, not just as a 1953-built chassis; period FIA papers and continuous racing documentation are supporting evidence, not proof of works identity.
