Temperature, a luminosity criterion, and two independent abundance indices are derived for each of 75 stars in seven open clusters within the Galactic anticenter on the basis of photometry on the revised Washington system. The spread in the individual C-M abundances in NGC 2158 and 2204 suggests that CN-strength variations occur among the giants in these clusters, corroborating earlier work. A comparison of the age-metallicity relations of NGC 2112 and Tombaugh 2 shows that the chemical-enrichment history of the Galactic anticenter clusters was far more similar to that experienced in the LMC than that occuring in the solar neighborhood disk. 48 references.
