To drill around broken stem or stuck tooling in well hole,
Appears to have 1 1/2" X 2 1/4" 8 or 15/8" X 2 5/8" 7 API pin tool joint thread,
Around 136" overall length.
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.
