Norton used the more rounded Doherty type. This one looks like Matchless, probably WD as it's unplated. The Bowden stamp is a nice touch. They usually aren't.

Could be Triumph, I had something similar with a canvas grip on it.

HI kostas, I think it is Matchless. If you decide to pass it on please contact me. Rewards John
