Up for sale is a vintage GTD (Greenfield Tap & Die) No. 0 adjustable tap wrench with the classic crown logo, made in the USA.

This is a genuine mid-century American machinist tool — likely 1950s era production — not a modern import. The GTD crown marking is crisp and clearly legible. Stamped “MADE IN U.S.A.” and “No. 0.”

Capacity:
Closes down to approximately 1/16” square
Opens to approximately 1/4” square
(Perfect for small taps #0 through #10 and many 1/4” taps depending on shank size.)

Condition:

• Clean, crisp stampings
• Jaw teeth are sharp and not rounded
• No cracks, chips, or abuse
• Honest light shop wear consistent with age

This is a solid, tight example that has not been heavily buffed or altered. Adjustment operates properly and jaws close evenly.

A great addition to any machinist’s drawer, restoration bench, or vintage tool collection.

Please review photos for condition details and feel free to ask questions.
