This is a K98 Mauser 8mm in a sporterized stock . Someone has removed the finish off it and it is kind ruff cosmeticly. The gun shoots fine and operates as it should.
There is a Mauser not sure the model that is missing the bolt . I was going to put the K98 in this original stock but you could restore it if you can find a bolt .  It appears to be a smaller caliber than the K98 8mm. 
the third rifle I'm not sure what it is maybe an Ariana or Carcano but it is missing the bolt and is pretty ruff .
