During the early 1970's the results of a routine circulation of some mass artifacts between several laboratories revealed unexpected systematic errors. Our interest in understanding these anomalies led us to undertake several projects that are soon to be incorporated into a new round-robin effort. We believe this new work will demonstrate that the mass unit can be disseminated through artifacts of less than ideal characteristics and the results remain free of serious systematic errors.
