The Frazier History Museum in Louisville, KY has a lot of high-grade 99s on exhibit (it used to be called the Frazier Arms and History Museum, but the PC pantywads talked them into changing the name). It's worth the visit if you're in Louisville for other reasons.
They have a lot of high-grade Marlins on hand, too, along with Teddy Roosevelt's Big Medicine .405 Winchester and his H&H double rifle, and all kinds of armor and other things, along with historical presentations.
