Newton24b, great information! Thanks.
Mp25ds4, Oh, the bluing came off. I did all the cleanup with a fine wire brush wheel mounted on one side of a bench grinder and a buffing wheel w/ rouge on the other. As for the barrel I just wire brushed all the rust off the really bad spots and used 00 steel wool w/ shooters choice on the rest of the barrel to remove smaller bits of rust. Then sprayed and wiped w/ gun scrubber heated the barrel to ~100 deg. and then rubbed it down with Formula 4440 instant gun blue (only one the local shop had).
