250 gal spring cooled tank, inner tank is good, outer tank is rough. If you remove the inner tank and build a support rack, then weld 6 bolt holes which are 5" below the top, it will then hold 250-260 gal. Those bolt holes are how the inner tank attached to the outer tank. If bolt holes are not welded shut it's about a 200 gal tank. Inner tank is good condition, outer tank is very rough, loads of dents and a few tears. Homemade SS covers $250, add $50 for valve. Estimated 850 gal SS outer tank, (inner tank was removed before I bought it) Rectangular inside and out, with shallow V shape in bottom. Interlocking homemade covers, no bottom drain, I used it as a woods tank and pumped over the top. $600. includes PT wooden cradle. 165 gal horizontal plastic leg tank with cover (6"?) bulkhead drain port on one end. Used to haul sap in my early day, later used to haul potable water. $150
