the last person selling them was a gentleman who owns Recon Ordnance Co. he goes by the name of Jerry (good Man to deal with). he is an old timer and does not have a Web site but you can reach him at 920 922 0737. his ads appear regularly in Shot Gun News.
If you really have an interest he may be able to point you in the right direction,
hope that helps.
BTW if anyone ever figures out where I live and wants to steal my firearms let it be known I have them in a gun safe with an alarm system a BIG Dog and a pump Shotgun ready to go. Oh can't forget the Mote, Barb wire and Teller Mines. ;)
