It was an amp made by one of Ampeg's engineers: http://www.keithrosier.com/jess.asp The creator of the Portaflex. Hold on to it. It may be valuable to the right person. It is rare. Is it a head or a combo? Speaker? Does it have a date on the tube chart? Potentiometer codes? What is the complete tube complement?
