Thanks a lot, guys.

I think it's almost certainly designed for a Zefal HP or HPX. At the end
of the pump head, those pumps have two sort of flat plastic pieces with
a concave curve cut out to fit up against a frame tube.

They're about 19mm wide and 3mm thick.

One of those plastic bits is almost, but not quite, axial with the pump.
It looks to me like it would slip perfectly into that slot.
