I have one. 34" flat rib, choked .029 I think. Will check and make sure. No porting. Very good, to excellent shape. Only bluing wear is under the forearm wood. Will get pictures for you in the morning. Will send a PM with my contact info. along with the pictures.
I know you're asking for just a barrel but I have a complete Mod 32 that I would like to sell. 34" top single with 3 Briley choke tubes. .025, .030 & .035. Less a case of shells through it since the annual. Don't know what just a barrel will cost but you might be surprised at the price of the whole gun. Let me know if you're interested. OtH
