I don't have Jacks latest version but nothing is mentioned about this pump in the earlier version so I suspect that is the case with the newest book.
Anyway, so far I only have 1/2 of the pump, which I acquired a couple years ago because I liked the original look and had the original ad glass yet.
I do remember seeing a couple other half's about 15 years ago and thought the base looked strange, but not into pumps much then so left them behind.
So I know there is others out there, just a matter of finding another half I guess.
