From the 1858 "Deanes' Manual of the History and Science of Fire-arms": In the breech-loading shot gun of M. Bernimolin of Liege, that eminent manufacturer, by a happy appropriation of the best elements of each of the various French and Belgian systems, produced in 1853 a new arm, which soon took a front rank place with the best of them. From the Lefaucheux he took the method of closing, and retained the lock mechanism of the ordinary percussion gun, with this difference, that the cocks serve no other purpose than to facilitate the play of the tumbler to cock and uncock the gun, on the same principle as in the Beringer pistol; the barrel, together with the mode of loading it, by means of cartridges with metallic bottoms, is an imitation of Loron's idea. The direct ignition at the axis of the bore of the barrel, as in Robert's, Montigny's, and Loron's guns, is effected by the disengagement of two small metallic stems, acting as hammers upon another stem affixed to the base of the cartridge, and on which the cap is placed ; the jet of flame from which comes consequently into immediate contact with the charge of powder.
Since the 1862 text refers to five different manufacturers' guns it is not necessarily specific to Bernimolin. Additionally even if the exhibition Bernimolins were hammered that does not preclude the possibility of a hammerless from them as per Deane & Georgens.
