It's interesting that neither chart really addresses your code. The chart you listed confirms mine is the 15122-001.
Yes, Lenco is saying mine is different, BUT, my end or Ram hole is 3/8" and I just confirmed the ram throw to be 1.25 " so mine has to be 15122-001 as well as this is the only one with a 3/8" hole. Otherwise I would have to drill out the 5/16 to 3/8.
