there is a current post about "uh-oh 27-2 not such a good deal". He found the rectangle with r-b in it under the grip panel. I have been reading the great information on this site for a few monthes. Today I registered to post a reply to warn you on that armslist add I can see the exact same symbol meaning it may have been reblued. $1100 seems like an awful lot if it has been.
