This Mercedes-Benz 300 SLR Junior is a superb children’s car, and a wonderful tribute to the sporting roadster driven to overall victory in the 1955 Mille Miglia road race by Stirling Moss. It is equipped with a 48cc engine, coupled to a centrifugal clutch driving the rear wheels, which can power the car up to a top speed of 15 mph. Braking is by a single disc with a mechanical piston caliper.

Based on an existing design by the builder, this 300 SLR is one of only a handful of ‘half scale’ creations that feature a plaque signed by Stirling Moss himself. There is a Certificate of Authenticity for the plaque, with a photo documenting the signing. The seller states that the mini 300 SLR should be suitable for most children aged between five and nine years old.

Its chassis is powder-coated steel to a bespoke design, while the bodywork is composite glass-reinforced plastic. The silver paintwork and red ‘722’ livery is a faithful replica of Moss’s Mille Miglia winner, co-driven by Denis Jenkinson. The bonnet and boot lid are both functional, and there are working headlights. It rides on 12-inch steel wheels with pneumatic tyres, finished with three-eared chrome spinners.

The cabin is a great tribute to the original car, with hand-stitched dark blue leather and tartan cloth panels on the seats. The floor is trimmed with grey carpet, and the edges and side panels are upholstered with diamond-quilted leather. Ahead of the driver is a four-spoke polished aluminium steering steering wheel, as well as a plastic aero screen. A brand-new Held helmet, finished to match the car’s livery, is also included.

This Mercedes-Benz 300 SLR Junior is a wonderful hand-crafted children’s car, which boasts superb attention to detail, not to mention bearing the authenticated signature of the great Stirling Moss as a finishing touch. It would be a fun addition to any collection of classic race cars or Mercedes-Benz models, but is of course ideal for a junior racing enthusiast to drive and enjoy as intended. It is a fun, faithful tribute to one of the most recognisable historic sports cars ever built.
