I have an opportunity to pick up this pump, but being a rookie I have no idea of its' worth, or even what it is for that matter. Fella thinks it is a Gilbarco, but I cannot find one like it in my searching the web. He also has the "Shell" globe which he says is original, along with all the porcelin signage. I haven't seen the globe to know if it just says SHELL or if it is the older one that is shaped like a shell. Can someone ident it and give a rookie a ballpark figure as to what it might be worth? Thanks......Louis
