The locks say Perkins,
best guess according to Boothroyd
Perkins, George, Birmingham, 1857-61
Pistol maker and gunsmith, 9 Lancaster Street, 1857-61
Gun, rifle and pistol maker, Loveday Street, 1862
that could be him, it about fits the proof marks, but anything you find out would be appreciaed.
over all looks like good mid quality piece, a ounce or two over 6 pounds for a 14 bore.
