We present a detailed, quantitative study of the standard [WC10] Wolf-Rayet central star CPD-56° 8032 based on new high resolution AAT UCLES observations and the Hillier (1990) WR standard model. Our analysis of CPD-56° 8032 gives the wind properties (T*=34 500K, lg (L/L⊙) = 3.8, lg (Ṁ/M⊙a-1) = -5.4, υ∞ = 225 km s-1) and chemistry (C/He=0.5, O/He=0.1, by number), the latter suggesting an intimate relationship with the O VI PN central stars and the PG 1159-035 objects. A comparison between the wind properties of CPD-56° 8032 and Sk-66° 40 (WN10) indicates that low excitation, low wind velocity WR winds are common to both low mass PN central stars (WC sequence) and high mass post-LBV's (WN sequence).
