Just by chance found out about 1 of the other dogs. I googled BRONZE RUSSIAN WOLFHOUND ( now that I found out what kind of dog this is) and a picture of "our dog" was listed at an auction house in New York. No answers to my emails sent last week so I called them today. The owner and his staff were fantastic and went above and beyond to give me the information on the auction that occurred over 10 years ago.
The dog was from the estate of former Texas Governor John Connally (for history buffs - the one riding with John F. Kennedy on that fatal day) and sold for $2,500 which he stated was low at that time. (Current estimated value $5,000 up.) It was purchased by a collector that he works with and has one of the most expansive and expensive collections in the country. He couldn't find markings on his dog as well and was eager to hear that it was from France.
Our friends' store was in Ft Worth, TX so we are willing to bet this is one of the triplets!
