Nomenclature on the top of the shank is "CHARATAN'S MAKE" over "LONDON, ENGLAND" and "SELECTED" just beneath that.
According to this article by Ivy Ryan, the Selected grade was second from the top, eclipsed only by the Supreme. Unfortunately this one no longer had the original bit, which may have had further nomenclature on it. Even without the bit, this is probably the most valuable pipe in my collection, and is yet another one that I am looking forward to getting fitted for a new bit.
NOTE: I first read the linked article on Charatan pipes some time ago and saved it to my computer. I don't recall where I originally saw it, but found this newer link just now. I did not know there was a Pipedia.
