There is a Browning Citori 12G for sale in an online auction near me. They have it listed as a grade 5. The serial number is 11534PM5B3. I looked on Browning's website and found the PM means it's a 1980, but I could not find what the 5B3 meant. Any help would be appreciated.
A quick look at my notes goes from 3B3 to 6B3. The 6B3 would be a grade VI would be a 12 ga Skeet. It is possible that the 5B3 would be grade V skeet. Not sure why I have no info on Grade V unless it was not offered that year, or special order. I would call browning and see what they say. Also welcome to Browning Owners, please stop by the new member area and introduce yourself. If you need anything just let me know, we are here to help. Thanks, Ranger6
