Everything they show has 220 on its makers label, but the only label on this one says 110 volts & looks like it came from a brother labelmaker. The instant you mention 110 volt, fleabay thinks its looking at 500 hp Western Roller irrigation pumps or the like. Only weigh a ton or so. Water a square mile of irrigated land from a 36" hole into the Morrison Acquifier, now damned near dry and 700+ feet down. 300 could reach it in the early 70's. Damn I wish fleabay actually had a search engine. > > Cheers, Gene Heskett Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
