I would go with a model 640 Husky Hipower which has a large Ring FN mauser action. I would look for one with a crack in the buttstock that was in relatively good shape and go from there.I would search Simpsons Ltd. and or Alan's Armory to find the action that you wanted.

Sometimes you can find a CZ on absolute clearance that has been abused. I would then research the living heck out of mausers to get an overview about them.

After that level I might look at the 1909 Argentine small ring mauser. They are nice but a little more expensive.

Thomas
