The one in your second photo in the case with light colored lining appears to be a Browning O/U trap gun in a Browning take down case.
The other in the case with green lining is a Browning BT-99 Single barrel Trap gun. Here are what I believe to be their descriptions from the list:
12 BROWNING LIGHTNING, O/U SHOT GUN, 12 GA. 48010S5
13 BROWNING BT99, TRAP GUN, 12 GA. 71D06295
When you click on the photo it brings up a much larger image at their site that is very helpful in identifying the guns.
