Does somebody have experience with Paul Demas guns or rifles? I consider to purchase their O/U gun model 1030. What kind is their quality?

Here is picture of that 1030 model, taken in Game Fair summer 2006 (middle of the picture): http://www.freewebs.com/finedouble/Eramessut%20Riihimaki%202006%20011.jpg
