If the 29-2 was refinished in June 1981, the new, liquid penetrating blue process (not carbona blue) would have most likely been used. This process results in a slightly blacker finish than the carbona blue process. Also, if the McGivern sight, action job, etc. were all done in June 1981, the 29-2 would not have been a special order. We will see what the letter says.
