OK, got a bit of a rare bird and I am trying to find some info on this. I know for a fact that it is an NYPD bar because I know the person who I got it off of and where it came from, but it has a 6Z designation instead of the normal 2Z on the end of the model number. I know the Z means a custom build, but the 6 is the oddity. I was told this may have been from a NYPD Marine unit. I saw a post from back in 2011 about a 6Z, but haven't seen anything else either here or on any other site. Any help would be appreciated. Thanks in advance.
