Alright, thanks for the additional information as to the locking...and reconfirming my dissatisfaction with not bidding! Very...very...cool! You saved me from having to go digging through my library until I found the patent. I remembered that the hammerless version Purdey that I shot closed with a great deal of authority. One did not want to get their fingers in the way of that lever closing. It seemed to gain a lot of momentum as that long lever rotated back around to close! Thanks again!
