blood hound,
It appears you've got a earlier 11707 that was purchased when Benelli was still selling them with the retractable stocks. The LE markings do not distinguish a 11707 from an M1014. The LE markings were orginally only used during the AWB period for law enforcement agencies but there has been a crop of LE marked receivers showing up lately and sold as standard 11707's. Benelli is probably just clearing out some old stock.
The civilian model M1014 was made during the AWB period and has an American flag on the right-side of the receiver, fixed choke, and a retractable stock that would not retract due to not having the proper grooves machined into the stock guide post (per AWB). This model was also limited to 2500 units and thus become the limited edition model that people sometimes talk about here.
Hope that helps.
