Frame pump to fit Bianchi?
 

I am rebuilding a 96 Bianchi San Remo for light touring and it has a nub on the head tube to hold the frame pump that fits under the top tube. Where do you find current production pumps that can be used in that position?
I am not trying to rebuild to original stock so I am not looking for an operational vintige pump. Just looking for a servicable pump that mounts using the nub on the head tube. I am repainting the frame so I would like to paint the pump to match at the same time if possible.

The Zefal HP-X comes in 4 lengths; I'll bet one would fit between the nub and the seat tube. A strip of velcro might be a good safety retainer.
