Why thank you Ryry. Any chance you can let me know if the tube is a 35mm or 38mm? Yours is a very fine example. Where did you get it? I don't know much about them except to say I think they were made in the days before the Shop-Vac acquisition of Goblin and that I don't think they were Goblin cleaners, I think they were branded for Goblin. The motor in a good deal of these was the Electrolux cylinder motor, but at least two styles of motor were used.
