Around 11" wide to drill top hole or fit inside 12" diameter well casing.
Short stroke rig may do well with this as it's only around 24" length.
Good API pin thread up top.
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.
