For cable tool spudder well drill rig stem string,
Conventional Prosser style,
This is a "blank" but looks like right size for 2" x 3" - 7 API thread.
Appears to be new/unused, but very old stock.
We are selling AS IS, but can cut a 2x3-7 thread on it for $100 extra cost if needed.
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.
