[Closed] old style Feedback Ultimate truing stand spare WTD

hi folks, I have an old style (cast base) Feedback Ultimate truing stand, and the clamp for the truing indicator has split completely on both sides. Feedback (2Pure) site doesn't show anything so modern, wondered if anyone had access to old spares like that, or a contact at Feedback that might dredge up the part?

Hard to describe, but it's a black plastic band that goes round the shaft that's just expired through age I guess.
