Were they expensive guns? Did you get insurance money for the theft? Not sure I'd spend $$ on a lawyer to get back a gun that is 7 years old and may be beat up anyway.
I'd contact the day shift desk sgt and see what he says. There might be a property master you have to go through. Any mail you send should be certified. Look on their web site and grab some high level names to throw around.
