i guess a pump could go there, sure. I asked about the bottle setup because by the mid80s it was pretty common for a quality frame to have 2 bottle cages in the main triangle and higher level loaded touring frames to have a 3rd mount on the underside of the downtube.
I was simply surprised to see the underside location but not the seat tube.

its a neat part of cycling history since it was short lived- 2 bottle mounts on the downtube without a seat tube mount didnt last long.
pretty cool.
