Yes, it would be great if the buyer asks someone, like Buck Hamlin, who really knows Lefevers and the Lefever partnership guns to take a look at the internals and externals of this gun to see if he can pick up the trail of who made it. The gun definitely has Lefever characteristics, like the thumb push opener, but in other respects there are features which are not like Lefever hammer guns. It is a beautiful gun, but may have been made by a fine gunmaker who wanted to borrow (without authorization) some Lefever patented features for the gun and therefore didn't want to put his name on it, since that would have directly identified him as an infringer of one or more of Uncle Dan's patents. As a gun of about A grade level, any gunmaker would have been proud to put his name on it, except for some special consideration like this. An inspection of the internals by someone really knowledgeable, as Ky John suggests, could provide important clues.
