Hello again Countrylad.
It was indeed Tina, a Triumph Tina, that was their first venture into making scooters for a while it was a 50cc belt drive but unfortunately it was another flop, the second scooter they made was either a 200cc twin but I can't remember the models name, although the name Tigress springs to mind. The BSA also made a similar model which was with a slightly bigger engine a 250cc and I think that was called a Sunbeam.
