I acquired a number of pieces Allende in an exchange with the Arizona State Museum. Some of these pieces had ASU catalog numbers. In addition there were some part slices that were used by JT Wasson in his research on allende and have wasson numbers painted on them. In addition the wasson pieces have a 12mm round white label stuck on them with the number 2893 (designating allende) and a letter combination such as IIID or IJ. I believe the letters designate allende individuals I, II and III and the letters A, D, J etc. are the different cuts off one of the individuals. All of these pieces come with an ASU label card.
