Wait till you fit brake reaction bars it will rub both sides... and have less lock!
It should rub on both sides there's something wrong!
A rough guess is the steering rack is not set up central you have more lock on one side than the other.
As stated by others Traditional Morgans are exempt from the front wheels rubbing at MOT.
The brake reaction bars on my Roadster had nice polished patches where the tyre rubbed on full lock. But as the patches were even in size and position I assumed it was OK.
The car passed 2 MOTs with them fitted and without any comment from the Test station.
If the rubbing isn't even either you don't use one lock as much as the other or there is something out of adjustment....
