Recess choked or possibly "tulip" bored . Not an uncommon thing to find but now an out dated procedea . Greener in his 1910 Gun and its development and other later aurthor's show illustrations . It was a method used to either add some choke to a cylinder barrel or to increase the amount of choke already there . From some readings I have done about the history of choke boring ,forgetting the numerous claims as to whom and when, leads me to suspect this form of choke boring may have preceded the system we all know to day.

Not recessed, jug or anything else similar, in fact the opposite of such. This choke is a constriction on the tube albeit with a flared muzzle. Most likely it is just a normal choke which has been messed with over 130 years.
I had one like this quite recently and when I mentioned it to my barrel man he had an immediate and obvious reason for it...but I forget what he said! Age is a terrible thing!

You are correct and I have mis read the original post .The word "constricted" not releived should have been the clue.
