1952 Dodge truck carburetor issue

A friend of mine has a 1952 Dodge truck with the 6-cylinder flat head engine. It has a single barrel Carter carburetor. He brought the carb and a rebuild kit to me to rebuild it. the kit is correct aside from the fact that it only comes with one accelerator pump. The carb has two. They are leather and are one unit with the shaft. In other words, one cannot change just the pump cup. Any ideas where to get the other pump? I will post a pic of the kit contents and another of the other pump that I can't find anywhere.
