I wonder if Lucian Cary didn't have something to do with the building of both of those rifles. Being that they are consecutive Pope serial #'s, both the same unusual barrel length and that Cary was such a good friend of Pope's makes me think that they were ordered at the same time by one person. Then being stocked in a similar fashion probably shows that the same person was involved with the build of both these rifles. Great rifles done by masters.
