This model is the RBA Collectibles McLaren TAG Turbo MP4/2C (1986) in white and red livery as driven by Alain Prost in 1986.
The McLaren MP4/2 was a Formula One car designed by John Barnard of McLaren for the 1984 season. An iteration of it, the MP4/2B, was used in the 1985 season, and a slightly updated version, the MP4/2C, raced in the 1986 season for McLaren. The car used an all carbon fibre chassis pioneered by the car's designer John Barnard with its predecessor, the MP4/1. The car was powered by a 1.5 Litre, 90° V6 TAG-Porsche turbo engine that produced (650 bhp (485 kW; 659 PS) in race set-up and up to 800 bhp (597 kW; 811 PS) in qualifying set-up i.e. with maximum turbo pressure. The MP4/2 was virtually unchanged in 1986, with the exclusion of some tweaking in aerodynamics which saw it dubbed the "MP4/2C".
This model is probably from a Spanish or European partworks. The body casting is basic, covering the general shape of the vehicle but with several additional plastic parts representing the mirrors, windscreen, steering wheel, seat, and suspension making it much better than, say, the early Onyx models. It carries few logos (Shell, Boss, Goodyear, SegaFredo Zanetti), has the racing number "1" in white on the rear aerofoil, and carries the driver's name "Prost" on both sides just behind the cockpit.
The interior is set out with steering wheel and seat (with racing harness in silver). The glazing is clear on this model.
All wheels are of a "racing wheel" type - solid one piece, black plastic, 6 spoke hub with a soft rubber "slick" tyre.
The base plate is black plastic and is marked at the centre top with RBA Collectibles and "McLaren TAG Turbo MP4/2C - 1986" at the bottom centre. The base plate is held in place with two tiny self tapping screws, one front and one rear.
I do not know when this model was issued. Its scale is said to be 1:43.
