Thanks Dean,
The chokes are IC and Modified, same as my Repro 20 and 12.
I do not know and have never cared about actual ID measurements as I have shot this Parker and two Parker reproductions(20 and 12) for many decades. If I can see it, I can usually hit it.
I am now shooting them left handed/eyed due to a recent operation on my right eye.
Two weeks ago, I dropped a pheasant at 40+ yards with the left barrel (muscle memory with no thought). My buddies were all impressed and I was just blessed.
