Kroyden's brick face irons were covered under a US patent issued in 1920 to Arthur Kraeuter.  A fair number of these were produced, designed to add backspin to the golfer's shot, before clubs with deeper grooves were ruled non-conforming effective on Jan 1, 1924.

This beautiful example has its original shaft and grip.  The head has been nicely cleaned up and shows little if any use.  The owners initials "HMR" are stamped on the back of the blade along with "J Monroe Hunter" the golf professional who likely sold the club.
