Described as "English," I believe it is actually Belgian. Sanderson's was an importer, known to sell Spanish doubles. The level of quality is obviously pretty good. I left a bid of $1700, and wound up the under-bidder. A thunderstorm brought trees down and I was without power and off-line. So it goes. Can anybody identify the maker?
