We have obtained high-resolution (lambda / Delta lambda ~ 34,000) CTIO 4-meter echelle-CCD spectra of three red giants in the remote anti-center disk cluster Tombaugh 2. Our preliminary results indicate a mild metal deficiency, [Fe/H] ~ -0.3, for a reddening of about E(B-V) = 0.3-0.4. Results for one star indicate a greater deficiency of oxygen than of iron or alpha -elements. Full results for all three stars will be presented.
