We present the results of an analysis of the WC10 central stars CPD-56 deg 8032 and He 2-113 and of their surrounding planetary nebulae (PNe). UCL Echelle Spectrograph spectra with a resolving power of R = 50,000, covering the wavelength range 3600-9500 A, were obtained for both objects. Expansion and radial velocities are derived from the nebular Balmer lines. We also present deconvolved pre-COSTAR HST H-beta images, from which we derive nebular angular sizes of 1.6 x 2.1 sq arcsec for CPD-56 deg 8032 and 1.4 x 1.1 sq arcsec for He 2-113.
