# Lotus 49B Rob Walker Racing Team No. 10 Jo Siffert Spanish GP 1968 Spark Model 1:43

> A resin 1:43 scale model car capturing Jo Siffert's Rob Walker Lotus 49B No. 10 at the 1968 Spanish GP — one of the most recognisable privateer liveries of the Formula 1 era.

The Lotus 49B that Jo Siffert steered under the Rob Walker Racing Team banner at Jarama on 12 May 1968 represents a precise moment where privateer tradition and aerodynamic revolution converged on the same grid. Designed by Colin Chapman and Maurice Philippe, the 49B was the revised version of the 1967 Lotus 49, bringing extended bodywork and high-mounted aerodynamic wings. Siffert's dark blue and gold car, carrying race number 10, stood apart visually from the works Gold Leaf entries that had switched to red, gold and white that same season.

## The Lotus 49B: A Stressed Member Revolution

At the heart of the Lotus 49B sat the Ford Cosworth DFV 3.0-litre V8, producing approximately 408 bhp and mounted as a structural member of the chassis — a concept that reshaped Formula 1 car architecture. The 49B variant, introduced in 1968, updated the original 1967 design with revised bodywork, a more pronounced nose and the addition of aerodynamic wings. At roughly 4,115 mm in length, the car was compact but aerodynamically aggressive for its era.

## Jarama 1968: The Last Gentleman Entrant

The 1968 Spanish Grand Prix at Jarama was the first World Championship round to feature high-mounted aerodynamic wings as a widespread fixture across multiple cars. Rob Walker, the last of Formula 1's great private gentleman entrants, refused to adopt commercial liveries throughout his career. His dark blue with gold pinstripe colours — worn here by Siffert on chassis number 10 — remained one of the most consistent and recognisable identities in the paddock. Siffert retired with a suspension failure; Graham Hill took the win for the works Lotus entry.

## Spark Model in 1:43: Resin Precision

Spark Model reproduces the Lotus 49B No. 10 in 1:43 scale resin, hand-assembled with photo-etched detail parts as standard across the range. The resin construction allows crisp reproduction of the aerodynamic surfaces — including the high rear wing that defined the car's silhouette at Jarama — while the dark blue livery with gold pinstriping is rendered in full period accuracy. At approximately 9.5 cm in length, the model is sized for serious display alongside other late-1960s single-seaters.

## In the Display Cabinet

At 9.5 cm long, the Spark 1:43 Lotus 49B occupies a precise slot in any late-1960s Formula 1 collection. It pairs naturally with works Gold Leaf Team Lotus 49B models from the same 1968 season, offering the visual contrast of the private blue-and-gold livery against the red-and-gold factory entries. For collectors following Jo Siffert's career, it anchors the Rob Walker chapter of his story alongside the 1968 Monaco GP — a race in which the same partnership delivered one of the most celebrated privateer victories in F1 history.
