I am not aware of any articles, but I know they sold Teddy Roosevelt a couple of shotguns which he mentions in one of his books. I believe the company existed well into the 20th century, and have seen catalogs on Ebay. I would be interested in seeing the Tordoff article or anything else that is available. My guess is that the railroad barons in St. Paul (J.J. Hill, etc.) bought some high-end stuff from them.
