The dipped locks seem to resemble those of a Rigby, but that is about as far as it goes. Seems J.P. Clabrough also used the Roger's action per this "Shooting Sportsman' article:
"By the 1880s the modern form of the double gun had emerged, and J.P. Clabrough understood that he needed a sidelock-based action. In 1881 J.T & J. Rogers were granted British Patent No. 397 for a hammerless, detachable, barrel-actuated back-action lock. (The Rogers Brothers were Brits who described themselves as “gunmakers,” although Crudgington and Baker described them as “action filers” in The British Shotgun, Volume Two.) On May 9, 1882, they were granted US Patent No. 257764 for the same design and assigned it to Clabrough. It was this design that Clabrough employed to compete against his major rivals in the US: British makers C.G. Bonehill, W&C Scott, and Greener. Not until later in the decade would US gunmakers make their presence felt in the hammerless market."
