Hello all, I recently bough this putter from a thrift store. It is milled with what appears to be a urethane insert. It has heel and toe weights milled into the face as well. No markings of any kind as to manufacturer or model. It has a graphite Muscle by Fenwick ultralight shaft and a golfpride softie grip. Any info would be appreciated! And by the way, it rolls like crap, probably a result of the weird shaft.
