I have a 12 ga Daly Miroku Superior grade. Nice gun but have never shot it well. Bought it in the orginal box for $125 at a gun show in the mid 80's. One chamber is slightly larger than the other, which was due to the original owner taking a 3" duck load and shooting in a 2 3/4" gun. Been thinking about making it a carrier gun for small gauge tubes.

Anyway, I don't think they would make a good project gun. You can still buy them fairly cheap as Jerry said.
