Slice a moulding cross section 1/8 thick or less, paint it black( if it is uniformly dark or light wood you may not need to paint the cross section), and then scan it with a flat bed scanner with a white cover(contrasting to the wood color). The contrast will provide enough resolution to create a usable image for even the worst raster to vector conversion progrm.
You can also insert the scanned image into most cad programs and use heads up digitizing to create a vector tracing. The trick is to use the part on the flat bed scanner and not a traced line. With heads up digitizing, you sketch points along the edges of the cross section and create lines, arcs, and spline/nurbs curves.
