Somewhere I have pictures somewhere of an amazing cross compound poppet valve steam by Scheuer. I missed iy by just a hair due to internet delay while bidding on German ebay on my office work station back in 2002 or 2003. The delay was enough that I entered my sniper bid after the auction had ended. His son G W Scheuer was selling some of his stuff. I got my first Stuart Beam from him. In addition to buiding model steam, he ownd a sheet metal fabricating company. I will try to find the pictures.
