Vintage Cast Iron “The Unbreakable” Golf putter head made in Britain

This is a vintage golf putter head made of cast iron. The markings “BRITISH MADE” and “THE UNBREAKABLE” indicate it was manufactured in Britain and marketed for its durability. The L-shaped design is typical of blade-style putters from the early-to-mid 20th century. The hole in the hosel would be where the shaft was inserted and secured. The weathered look and rust show its age and use.
