This 2-face croquet style putter was likely made prior to 1910, when the R&A made croquet style putting non-conforming to the rules of golf.  This club does not bear a makers name, and no other examples are known to the auctioneer. 

The head is well made despite the fact that a small nail was used to attach the head to the shaft. Each of the two faces has a slightly different loft from the other face, which gave the golfer options, and the club will stand on its own when placed on a flat, level surface, despite the fact that the sole is slightly cambered front to back, to help prevent the leading and following edges from catching on the turf during the stroke. This shows the club is well-balanced with excellent design engineering.

The shaft appears to be the original shaft, but the grip is missing.  An old replacement grip would be east to install, and this club would look great!
