"I deciphered the Citori I just purchased using the "Date Your Gun" section at the Browning website. Look under the "Services" section.
I could figure mine out to year, but not model of Citori. The "J53" suffix was not at Browning's site. One call to Browning and I found out what I suspected. A 3" chamber Hunter (field) model.
Happy Hunting"
I hope this helps you. I'm going to add this to my serialization chart. I'm willing to believe it without calling Browning.
