Dunlop Road Speed RS5 6.40-15 tires wanted

[Classics4me]

  Looking for 5 new(NOS), or like new, Dunlop Road Speed RS5 6.40-15 tires. I need them to be tube type tires. Their date codes, if they have them, are unimportant. They can have black or whitewalls, but they must all be the same. I will purchase one at a time if that's all I can get. At that point I would obviously have to choose one style and go with it. The tires cannot have cracks in them. They must be useable.   

  These tires were used on a number of '60s and early '70s era Jaguars and other vehicles.
