Here are some photos of an Adco Orange Crush dispenser. This was simply the valve; all of the syrup and carbonation would have been under the counter. Most likely it would have been positioned on the soda fountain, with the back facing toward the customers sitting at the counter. The orange-colored stand was something we made and was not part of the original dispenser. Our restoration was minor, but included giving it a good cleaning, replacing the drip tray (which are always missing) and making the before-mentioned stand.
Adco was a fairly minor player in the soda fountain dispenser business, but they manufactured some interesting and now very collectible pieces.
