for well cleaning / drilling with spudder pounder percussion or pump hoist rig.
Mud scow, sand pump, specialty bailer, not sure.
Roughly same diameter as standard steel water well casing (6-5/8") and around 76' long.
Presumably American manufactured with carbon and/or alloy steels, but unsure if this is Acme, Spang, Gill Rock Drill, Ideco, Trident, Rampp, O.W.S. Co., Keystone or maybe another historical tooling manufacturer.
If you require thread protector(s) on tool joint(s) add another $15.
