# Mercedes-Benz W125 No. 4 Seaman Donington Grand Prix 1937 CMC 1:18

> The CMC 1:18 scale model of the Mercedes-Benz W125 documents Richard Seaman's appearance at the 2 October 1937 Donington Grand Prix, race number 4, in bare polished aluminium Silver Arrow livery. Die-cast metal with photo-etched and turned metal detailing makes this the definitive pre-war GP piece for British and international collectors.

The 1937 Donington Grand Prix brought the full might of the German works teams to Britain, and Richard Seaman — one of the very few British drivers contracted to a German manufacturer in the pre-war era — lined up for Mercedes-Benz in car number 4. CMC has fixed that specific moment in 1:18 scale, reproducing the W125 exactly as it ran on 2 October 1937 at Donington Park.

## The Most Powerful Grand Prix Car of Its Era

The Mercedes-Benz W125 was developed for the 750 kg Grand Prix formula and is widely regarded as the most powerful Grand Prix car of the pre-war period. Its M125 engine displaced 5,663 cc and employed a Roots-type supercharger, delivering extraordinary performance by the standards of the era. The chassis itself was technically progressive: the W125 introduced a De Dion rear suspension layout to Mercedes Grand Prix engineering, a first for the marque.

## A British Driver, a German Silver Arrow, a British Circuit

On 2 October 1937 Seaman started from the front row in car number 4 but retired after a collision with Müller's Auto Union damaged the rear suspension. Bernd Rosemeyer won the race, with Manfred von Brauchitsch second and Rudolf Caracciola third. Seaman's presence as a home-nation driver in a German works car gave Donington an unusual narrative weight. The W125 carried no paint — the Silberpfeil livery was bare polished aluminium bodywork, the visible expression of the German racing colour of the era.

## CMC's 1:18 Scale Model: Die-Cast Metal and Photo-Etched Precision

CMC (Classic Model Cars) produced this model in 1:18 scale using die-cast metal as the primary material, supplemented by photo-etched metal components and turned aluminium details throughout. This multi-material, multi-piece construction approach is characteristic of CMC's methodology for pre-war and early motorsport subjects, where external mechanical complexity — exposed exhausts, supercharger intakes, open cockpit coaming — demands a level of part count beyond standard die-cast production. The livery is specific to car number 4, Donington 1937, making this model unique to that event context.

## In the Display Cabinet

At 1:18 scale the W125 demands a generous shelf depth given the car's open-wheel, long-nose Grand Prix proportions. The natural companions are the Auto Union Type C of Bernd Rosemeyer — the race winner on the day — and later Silver Arrows such as the W154 or the W196, tracing the unbroken line of Mercedes Grand Prix development. For collectors focused on British motor racing history, the Donington provenance and Seaman's number 4 position this model as the centrepiece of any pre-war Grand Prix display.
