Washington photoelectric photometry for 136 stars in nine old open clusters is presented and used to determine the luminosity class, T(e), and metallicity. The virtually unstudied cluster NGC 2324 is found to have a metallicity one tenth that of the sun, as is the cluster NGC 2660 for which previous estimates have ranged from about +0.1 to -0.5. A third cluster, NGC 3960, with a Galactocentric distance of only 8 kpc, is found to have a metallicity of -0.7, also substantially lower than published values. Such clusters indicate that substantial scatter actually exists in the tight relation found by Friel and Janes (1992) between the metallicity of an open cluster and its current Galactocentric distance. Outer disk clusters have a metallicity at a given age that is much more like that of the LMC counterparts than that of solar neighborhood disk field stars or clusters.
