William Mills was the most prolifice designer and manufacturer of late 19th century/early 20th century aluminum head golf clubs. He created The Standard Golf Company, a division of The Atlas Works, to produce his clubs which are commonly referred to today as "Mills" clubs.
Marked "Mills RB Model Straight Face Brassie" etc. on the sole, this Mills meta wood has its three original wood blocks inlaid in the back of the head. Produced early in the 20th century, this club still looks like it can play!
