1967 AAR Eagle Mk I Gurney-Weslake (chassis 103)

Formula 1 has plenty of beautiful failures. The All American Racers Eagle Mk I is the rare American chapter that still rearranges the room: Len Terry monocoque thinking, Goodyear ambition, a Rye satellite shop next to Weslake, and Dan Gurney’s insistence that Santa Ana could build a Grand Prix car. Four Formula 1-specification Mk I chassis were laid down. Three of them received the 2,997 cc Gurney-Weslake DOHC V-12. Chassis 103 is the second of those V-12 cars — a works car from a production run you can count on one hand.

The period book on 103 is not a single highlight reel; it is a season of almosts that still matter. Richie Ginther debuted the chassis at the 1967 Race of Champions at Brands Hatch (heats and a late-race retirement that still classified him). Monaco that May put Gurney in 103 after a chassis swap in practice — fuel-injection belt failure after four laps, and Ginther’s last appearance in a racing car when he failed to qualify the sister machine. After Spa’s famous Mag-Ti win in chassis 104, 103 returned for the Canadian Grand Prix at Mosport: Gurney qualified fifth and finished third in the rain behind the Brabham-Repcos. At Monza, Ludovico Scarfiotti took over 103 while Gurney ran 104; both Weslake engines expired early. That is enough documented GP grammar for an original dossier without treating the auction catalog as scripture.

Post-F1 custody — Danny Ongais’s unrealized Formula A plan, later California and Florida private hands, Ben Liebert’s Goodwood and Monaco Historic outings, then long private collection since 2002 — belongs in the provenance notes, not as a substitute for the 1967 race record. RM’s Sealed September materials also flag a Hall & Hall view that the car wants proper race preparation before further use. What matters here is the significance and survival of the type, not a promise that it is grid-ready tomorrow.

Why it rates so highly: absolute works production, American constructor lore tied to the only American-built F1 design to win a World Championship race (Spa 1967, sister Mag-Ti 104), and chassis-level driver history. Score 94 — Ultra-rare band. Production/survival near ceiling; specification is the correct Weslake V-12 Mk I; provenance is period GP; documentation is deep in secondary literature; market appearances of Mk I V-12s are exceptional; condition points tempered by prep needs.

Watcher’s checklist

1. Confirm chassis plate 103 and Weslake V-12 identity with a specialist (Hall & Hall / AAR literature).
2. Separate period 1967 race entries from later historic-racing participation.
3. Budget race prep honestly — sealed catalog language is not a fresh build sheet.
4. Sealed results stay private, so there may be no public price to compare against.
5. Check RM Sotheby’s for any published result.
