There are other medals for the hope box that I have. The Chinese Junk Keying, one with just type instead of the POW. It has been suggested that there is a five and six set box, I have yet to see one. Given the existence of the Keying Junk medal that is identical in all ways to the others already noted for these boxes, ie, weight, size, it would seem probable. The internet has changed so much in the way of greater shared information from a decade or two ago, when Rogers book was created.
