I’ve got an MTS-102, not sure what the difference is other than it being all silver? It does say 22mm on it (as opposed to 22.2) but is a snug enough fit it a standard steerer as far as I can tell. £25 posted.
I saw a 120 last week at a bike charity hub in Perthshire. Looked in decent condition. I’ll pop in again this week and grab it for you if no one else can help.
