I will take $400 each (plus shipping) for these. They are NOT a matching pair if you are considering buying both. One has the mercury logo on the plate and the other has the Kiekhaefer logo and some other differences. These are new (thats why the blue tape is still on them.) Back when I bought these, I assumed they were a matching set and never opened the box till months later. No pumps, just what you see in the pictures.
I know there have been quite a few people looking for just the cylinders but I dont want to seperate these.
