Your Cross gun fits into the category, "Lever-cocked Hammerless gun." It is a very early example of this type of action. Records show that; Thomas Danby Cross, James Wheeler Cross & William Wheeler Cross, were granted British patent No,126 of 1879 covering the action of your gun.The Cross partners [perhaps brothers] named in the patent are described as gun action-filers.One might speculate that on the basis of this patent, that the partners went on to establish the gun making business, described by others.
