I have one. These are the only other two I’ve seen tho. These appear to be engraved by Bill Stroud also which would make them 1972 or earlier. Dick Abbot had these for a while on his site billiardcue.com. I think he said a very old guy owned both maybe the one I have as well. I think maybe he passed? I think Dan refinished both about 10 years ago. Nice cues!!
