The bluing can be taken care of and that would be the least of the problems. As James stated, this gun has the type 1 ejectors that used the mainspring and cocking rods to eject the empties. They are not made anymore if there is a problem with the kickers. They did make 2 with 29" barrels whether this is one who knows unless seeing it in person. The stock I believe is also a replacement. Still a nice gun to own after that Pachmayr recoil pad is replaced. After 1912 the No.3 was discontinued.
