Grip
It looks 70’s-onward to me – too modern for the Meteor or Sabre.
The Sabre grip has the cut-outs to orientate the grip in the grip itself, not on the column top. The cut-outs are also much smaller than those in the pic.
The Meteor has a deep (electrical) socket with slots for two tongues to engage into for orientation so is completely different from the one pictured. It also has a spigot around which the stick top is clamped and this is plain, not a threaded portion as in the pic.
