Not knowing how many variations of the Chilean Mauser were made, or which variation you're referring to, the assumption will be made that you refer to the Mod. 1908, which was a variation of the German Gewehr 98 Mauser. This stock, and stocks of other variants (such as the Argentine Modelo 1909) should have some degree of interchangeability with the Mod 1908, although it is possible that some sanding or other minor alteration will be necessary.
The butt stocks should interchange but the fore arms will not.
A savage 755 is the same.
Stocks for the 1200, 1400, 1500 should interchange. Nummrich (gunpartscorp.com) has synthetic stocks in stock.
Sometimes they will within a particular model.
