No idea. Repaired in 1975, The damage would suggest the wingtip hit something but there is no obvious repair in the wingtip. It's been flying with the repair for 37 years. The repairer has become a residential address in Houston.
The owner at the time was Nolan Atchley of Livingstone, Tx. maybe he knows what happened. It would be great to hear from him if he is still around.
