Well, since no one is answering, I'll offer some thoughts.
As with all things old Savage, if you see one for sale and you've been looking for one for forever, and you don't buy it, you have a screw loose. They aren't making them anymore you know.
And, did I mention they aren't making them anymore? So yes, they are squirreled away in private collections. They're not sitting on a shelf at Walmart waiting for you to walk in and snatch them up. After 100 plus years, they are most definitely squirreled away in someone's collection! You're going to have to wait for someone to die manny.
I probably sound like a smartass, and usually am, but manny you already answered your own questions. If you almost never see them for sale, they're either rare or they don't exist. Or I guess you could be a bad searcher. LOL
