My advice on these make sure you handle and operate one before putting any money down. The case-colored field grade you referred above is $1000+/-100 gun. Typical hunter in Europe will pick modern vertical barrel Beretta or Miroku over one of those any day. I would say the only premium game gun with different mechanism would be European O/U with side opening lever. I would pay premium over one made either in Belgium or England.
English would be John Dickson & Son, Edingburgh in North England or Zenith gun by Robert Churchill, London. The European variety was called Superbritte and was is? made in Belgium. Griffin & Howe usually has couple to took at if you're interested.
