Walraven photometry has been obtained for a sample of 43 metal-deficient halo giants and 35 stars with known values of Teff, log g and [Fe/H]. A calibration of Walraven photometric indices in terms of θ = 5040K/Teff and [Fe/H] is established. The metallicities derived for the sample of halo giants are in good agreement with those of Kraft et al. (1982). In contrast to the metallicities derived by Bond (1980), the authors find a considerably lower number of stars with [Fe/H] < -2.7 dex. The calibration yields a metallicity of -2.9 dex for CoD-38°245, which is in contrast to the extremely low value of -4.6 dex based on a spectroscopic abundance determination by Bessell and Norris (1981). The importance of this star for the calibration of photometric metallicities in the domain of extreme metal deficiency is discussed.
