Here are a couple variations of Seymour code PL-NA Three Leaves. The top two are pretty much the ones shown in Dale's book. The two on the bottom are somewhat different. On the bottom chips the leaves have much more curve and pointer tips with a heavy handed wiggly straw that grows out from between the leaves. That line almost touches the top leaf. The red and blue chips are similar to one another except the little accent lines near the bottom of the stem are in much different locations. Also the ring on the bottom chips is just a nick larger than the top two chips
