Tyco Grand Prix Set (Hitchin SG5)

This has been in our loft for 30 years - in case the grandchildren were interested. It is in less than ideal condition. The cars' wheels have perished and I have no idea whether they will work or not. It is a different scale and size to Scalextric so will probably only be good if you have an existing Tyco set or are willing to try to restore it to working condition.
