Depends on how choke markings on the weapon.
On the choke tubes. It is marked by lines on the front edge of the choke. The more lines the more open the choke. 1 line is a full and goes from there. If it doesn't have tubes, on the inside of the receiver near the bbls.
The markings on the receiver and barrel will tell.
The fixed choke markings are denoted by * marks on the bottom of the barrel under the forearm assembly. 3 on the left barrel and 4 on the right. *** Modified choke **** Improved Cylinder
Check on the barrel flats
on a single shot barrel you must remove the barrel and look at the flat side underneath the chamber to see the choke stamping.

We are not familiar with a model 22, but all Browning Shotguns use the invector screw in choke tubes. These are available at most Gun Shops and retailers of Browning guns. You can also find them online at the Browning Co Website
Haven't seen that marking. Choke markings on Browning shotguns are coded by a series of asterisks and dashes. They also had a marking called 'ACIER SPECIAL' which simply means special steel, indicating the gun was suitable for smokeless powder.
I don't think there is an invector plus model. Invector Plus is the choke system Browning uses on newer shotguns.
