Obviously I do not follow this forum often enough. I am the Steve Nelson who is currently rebuilding the Alex Henry .360 DAMASCUS double in question. No one seemed to mention the one factor that made this project worth pursuing, that being the Damascus barrels. Thanks to a very generous client (Mr. Buffum) I have a head start on the locks. No promises, since I have a couple (!) projects for my clients but I plan to have the rifle available for viewing at the Beinfield (Firearms Engravers Guild of America) Exhibition in Las Vegas, Nevada, in January, 2014.
