The problem with the Frazer steering wheels in 1951 is the same problem that Kaiser plastic wheel have. Most of the different types of plastics in use back then had problems with prolonged exposure to sun and heat. Rather than warp (like a model car of similar production date) the wheels cracked, brittled and literally began flaking apart. The Tenite material used was considered one of the better quality formulations of the day for decorative applications.
Unfortunately, there seems to be so little demand for re-running the steering wheels (we're talking sales of over 100 wheels either in pre-orders or within 6 months of production, at a price of between $200-300 a wheel, perhaps more) that the odds of finding a good wheel are all but nil.
