if you collect technofix this is one of those cross over items in this case using the cars and a unique track in vac form plastic with tinplate bridge , ,there should im sure be 2 or poss 3 cars but i only have the one its number plate is HWN1964 instead of the usual technofix number and it also has the number 3 on the roof , standard technofix cars will fit as long as they dont have the drop down bit , vac form is excellent and has another track toy printed on the base they must have used up printed plastic sheets 54 x 34 cms approx comes with original key also
box is complete but a bit soiled few signatures and it has some damage to the lid on one side im sure it could be pulled apart and reglued anyway there it is a rare technofix cross over item in 30 years of selling technofix and other track toys have only come across a handfull of the HWM series
