This is a very rare putter. The golf ball was added for contrast in the photo, but the head is a small semi-mallet type, and the face balance allows for focused and stable putting. The weight was 471g on a household scale. The grip is original and in very good condition. PING is synonymous with Manganese Bronze. For those who find the Anser type difficult but want an old putter that's not like everyone else's... please give this a try.
