I bought a brand new Triumph T140V from Whittaker's in Blackpool. (We later had a bit of a falling out as they would do feck all to help me with a warranty claim after a partial seizure, but that's another story). He had a whole row of obsolete Manx Nortons in the shop, that he had taken in part ex against modern wizz bang thingys, no such thing as Classic racing back then. He probably gave very little for them, an astute investment or what? I wish I'd taken a photo.
The number plate on the Triumph had 2 numbers transposed. I only found this out at a roadside check, when it was pointed out to me by a policeman.

He thought
he'd made a mistake checking the number over his radio, I didn't put him right!
