1967 Sunbeam Alpine

1967 Alpine 4 previous owners.
Everything works- windows, locks, lights, overdrive.
There is a paint blister on the off side front wing and the paint is peeling on the same arch slightly.
The gearbox needs topping up with oil every month, I suspect it is the oil seal which needs replacing.
There is no history other than old mot certificates.
There are no VIN tags on the car, I have the log book in my name.
Have had it 2 years, runs very well used regularly just want a change.
