Oldest MGB in Motor Sport

I am going to see an MGB project car with a competition history that goes back to around 1962. I believe the car is only about 4 months into the start of production. It is pretty well shot but it might actually be the oldest one out there with period competition history. If it is I feel it would be worth doing. So question is of all the known cars which is reckoned oldest with competition history? I understand that private individuals were out there racing them before the works cars emerged....
