I've had this posted on Bernard Levine's ID sub-forum with little success, so I thought I'd try it over here. A few folks thought it may have been from Bowen Blades with a later tooled marking instead of the hand-marked work of Tilton or James. I don't see a connection there and to me the markings looks like a lowercase "fjd" connected. Any help would certainly be appreciated, as I'd really like to quit looking at it from every conceivable angle trying to figure it out.
