I think if anyone can get the green stain right, it should be Ireland's Peterson. Several years ago, I bought a green stain billiard, not a Peterson but a Chacom, which was reportedly made especially for Iwan Ries. I will say, it has been a fine pipe, but also, the green stain has remained bright over four or five years. Some have complained that some green stain on pipes tends to gray-out over time, although this may also be the product of hard smoking, humid environment, or grease and dirt in the handling. There is something riveting about the simplicity of the straight billiard shape. The depth on the bowl of the one in the original post is impressive!
