Zefal HP-X size 3 pumps fit my 55cm frames along the seat tube.
Since the 1960 Capo has a Rathausmann copper badge on the seat tube and downtube pump pegs, I found a blatantly period-incorrect Mt. Zefal 16-incher which serves well. For the UO-8 I found a slightly longer Blackburn pump with fits the downtube pegs, and which works far better than those great-looking, poorly-performing Zefal cigar tubes with the detachable screw-on hoses.
