This is the rare Schenectady-style center shafted MacGregor WW putter. Stamped on the crown with its patent date - Oct 21st, 1919. The putter has a large brass back weight, and the face has a brass face plate. The shaft is stamped "The Crawford McGregor & Canby Co." - using the prior spelling of MacGregor which would've been recently changed shortly after 1919. Excellent condition.
