Congrats Guy on getting such a fine rifle! Having an original or contemporary master's work in your own shop to be able to handle as a study piece is invaluable. There is so much nuance in architecture, lines, transitions and how they all blend together that much of it does not get conveyed in a picture from a book. Also, depth of carving, engraving, and their composition. Being able to pick it up and see how it should feel and if the Oerter you're building in your shop feels the same way. Keep them calipers and a ruler handy when you're doing it, it's surprising how tiny little inaccuracies can throw the whole look and feel of a rifle off.
I'm sure it'll be a great shooter as well.
