Help finding builder of Taylor frame

I just received a new to me frame via UPS earlier this afternoon and it was a real surprise at how well made and light the frame is. It was sold to me at a half carbon (top tube, down tube and maybe seat tube) and half steel frame (rear triangle and head tube). The brand on the frame is a "Taylor" but so far I have not been able to locate a "Taylor" company or builder that might have made this. The carbon down tube is a oval profile and the carbon top tube is a round cross section. I have found a Jack Taylor company and a frame builder in the UK named Angus Taylor but neither seems to have ever made a half carbon / half steel frame like this with this particular font used on the Taylor decals.

Anyone ever heard of this? I would like to know more about the builder and the approximate year of the frame.
