Stan, if you find a "good" gun in all respects except choke have you considered having permanent choke tubes put in the gun? Mike O can do this if there is decent wall thickness. Your gun might be out there but finding it is going to be hard. Too many guns have been opened up, barrels bobbed, abused and neglected along the way.
You might be better off searching web site in GB for what you are looking for. Then just have it imported. Several dealers who post here could handle the importation for you. A few of our British posters might even be able to suggest where to look.
