I own one I purchased from the original owner. He said he purchased it in 1966 from a walk in salesman (he was a dentist) for $250. It sat in the dentist office till about 1975 and was then stored in a heated garage until I bought it in about 2002-2003. Its cloudy but will clear up when you let it sit, it goes crystal clear but as soon as you run it, it clouds. I have been unable to break the seal at the top as I would like to try to clear it (filter pump).
Im not sure where I got this picture, I know it was from here but im unsure of the member who originally posted it.....it shows the price of $149.50 and the 3 color choices
