I bought one recently, it's a 3" 13-2, serial 8D72xx. P&R with the proper RB magnas. I may letter it to see if it's a FBI gun, but I am guessing it's not considering the condition it is in.

I know of a place locally I can buy a 3" 13-3, it's not in as-good of a condition as the 13-2 I bought, I would say 85%
