HI!... Picked this up off Ebay a few weeks ago. It was advertised as a Tamiya F-1 bumper. I bought it since it looked like the bumper to go on my Tamiya Honda F-2. These are white though. Never seen a white set.
Apparently they are from this, and extremely rare in white.
Released in September 1982, the Brabham BT50 BMW Turbo was the last Tamiya F1 model with the tried and trusted flat pan alloy chassis. Like all the competition special models, this car had good speed and handling and in the ever increasing hobby of RC racing was a perfect beginner's car.
The body shell, as always with Tamiya models, was exact in every detail to the original F1 racing car, right down to the wing mirrors, which are now almost impossible to find if replacements are needed.
The Brabham BT50 BMW Turbo was not produced in great quantities, hence the extreme rarity of this Tamiya classic. This makes the car very expensive to collectors. Occasionally one will come to auction, but at a price. If someone is rebuilding and they struggle to find the white set they are then forced to used the more common black.
Has all the wheels an tires thank god,and i was looking the front wide inner wheel halves then remember the skinnys use them too 
duh brain fart
