Vall,

"stock pads" is Savage collector lingo for the flat places on both sides of the butt stock behind the receiver. On most 1899's, they are pointed like the one in the auction, and short. The 1895's are longer and rounded at the ends. A few 1899 carbines don't have any pads, just a rounded profile from the receiver into the wrist.

David Royal from Pinedale, WYO just put out a new Savage 99 book for collectors. It is a nice book, covers a lot of models.
