  We question the reliability of current estimates for the Delta(+) mass. We
explain why the standard value, determined from pion photoproduction, should
not be used in conjunction with present estimates for the Delta(++) and
Delta(0) masses, determined from pion-nucleon scattering. The resultant mass
splittings are internally inconsistent. We also briefly comment on
discrepancies found when `theoretical' and `experimental' values for the Delta
masses are compared.
