Regarding Peanuts it appears that at Exterminator’s 30th birthday party they were on Peanuts the 3rd. BP May 28 1945
Twenty-seven years have elapsed since Exterminator won the Kentucky Derby. But the greatest of geldings of his era still is a hero to hundreds of Triple Cities children.
They brought gifts to his birthday. Bunches of carrots, packages of oats and sugar. Yes, even sugar, scarce as it is these days. Why, one youngster handed
caretaker Mike Terry a can of lump sugar, proudly saying, “Here’s Exterminator’s birthday present.”
Children alone didn’t go to Sun Briar Court. About half of the 300 who went there to pay tribute to one of the greatest race horses in American history were adults. “Old Bones” will be 30 years old Memorial Day. Because of the nature of that day and since many of the youngsters would be out of the city then, Mrs. Willis Sharpe Kilmer gave Exterminator his party yesterday.
He seemed to enjoy it as much as the children, too. He arched his noble head proudly as Terry and Superintendent Peter H. Curran led him over to the table on which were displayed the many trophies he won in his racing days. You felt as if you could see a smile on his face as people stroked him or handed him a lump of sugar.
And in the paddock he was as frisky as his pony companion, Peanuts III
The fact that many of his back teeth are missing—his age is equivalent to 90 in a person— didn’t stop him from wading in, either, when Mrs. Kilmer fed him the birthday cake.
The cake was of mash and carrots, trimmed in green. That made the green, orange and brown of the colors of the racing stable of the late Mr. Kilmer.
Following Willis Sharpe Kilmers death his surviving wife (Sarah Jane) would remarry in 1949 to Eben Howes Ellison, Jr. and would continue to race horses under her remarried name. Such a horse was Sun Bahram - who was out of the Kilmer mare (buried beside Exterminator) Suntica. Before being remarried she would sell the Riverside Drive mansion and oddly per a 1958 article the mansion was sold to the subsequent buyers with many of the trophies earned by Exterminator, Sun Beau, Sun Brier, etc. included.
She died around 1985.
Another interesting read is the often mentioned “Back the Attack Day” at Belmont Park which Mrs. Kilmer agreed at the request of the track to have Exterminator (at 23) come down from Sun Brier Court for the big day.
Sun Sept. 25, 1943
Belmont’s plan for Futurity Day calls for an admission price of one $25 War Bond. The "charge for the clubhouse will be a $100 bond.
Exterminator will leave Sun Brier Court In a horse van next Tuesday morning. He should reach Belmont at about 3 p. m. Peanuts, his pony companion— they are inseparable—will go along, too. They will be watched over by Mike Terry, caretaker for 25 years of the country’s outstanding cup horse.
This will be the second time Mrs. Kilmer has permitted Exterminator to go for a trip for a gala racing event. Two years ago he went to Pimlico, M.D. to lead the field in the parade to the post for the Exterminator Handicap, a race named in his honor.
The “Back The Attack” at Belmont was the single largest War Bonds raising event: Life Magazine Oct 22, 1945
[Exterminator being there] is credited with selling $25 million worth of War Bonds.
