Two CD 252 McLAUGHLINs in light green with tiny sharp drip points. Their are also units in light green with large round drip points that I am looking for. I wonder if the large round drip point units are the apple greens? I am learning that they are only a shade or two off from the light green and the emerald greens are all the large round drip point. Only a thought ! Any other thoughts or facts out their.
