thank you neil, i really appriciate your help! do you know where i could find any photos of this pump? so i can find out what it looked like and what color it when it was new? and if it originally had any advertising on it? and i thought it was weird both the front and back have no glass inserts they or advertising on them? it looks like there might have been a cirlcle about 6 inches around under the glass on one side?
