Hi Jerry,
If I recall correctly, this is the Navy this shop has had FS for sometime :

More importantly, if I recall correctly, one of our Forum members had tis one sent to his home for a possibly buy. It went back the next day, as I recall it had the small rear toggle pin flange set-up. That info. was conveyed with the return of the gun. But no change to the FS ad was made after that transaction or it its asking price...
