I originally posted this in the Regulators forum but nobody seems to know what it is? It looks familiar to me but I just cant seem to place it. I picked up up in box of equipment given to me by a friend it belonged to her late father. It has 1 Hp and 4 Lp ports and may have been matched with an old Tabata second so it may be Tabata/Tusa but I am just guessing. The Yoke screw looks very familiar to me but I just cant remember where I have seen it before.
