This is a rare, long out of production folding stock for a 10/22.  It was made by Federal Ordnance as far as I can tell through research.  It has not been modified with a forward swivel mounting point like others I have seen.  It comes with a black sling. I have more pictures available.  It is available for pickup in North Ridgeville or we could meet somewhere nearby or at a local gun show.  I will consider shipping it if necessary.
