Swack- fair comment. I have had access over the years to an English publication , if memory serves me right that had origins in the 1790s. There are etchings of these dogs in that period stated. i THINK (?) it/was called Sporting Times. The University of Minnesota , Vet school should have it because I found it misplaced in the Science Library on a locked 4th floor (1986). . The short and long of it, there are period paintings which I have seen @ the Washington , D.C. mall museum complex by English artists showing these dogs as well as etchings and photographs.
