An LTE abundance analysis of the "CH-like" star BD 348, with an unknown evolutionary status, is presented based on high resolution, high signal-to-noise spectra. With [C/Fe] = +0.5 dex and a mean s-process overabundance of [s/Fe] dex the peculiar atmospheric composition of BD 348 is confirmed. The modest iron deficiency, [Fe/H] = -0.8, and the kinematic data support the idea that BD 348 is an old disk population object. Possible evolutionary stages, that can explain its atmospheric parameters and peculiar chemical composition, are discussed.
