the action is very much like the original oberndorf slant box made for rigby in which they have a mag box angled as to let the rim of the cases sit in front of each other to feed properly ,the siamese were mostly converted to 45-70 .these actions resemble the 303.rigby or the 400/350 rigby
the original bottom metal is good looking and can be made to look much nicer than most mausers with a little work....paul
