First off Kudos to Clay to provide the requested photos. A couple of random thoughts. I do not see a proof date on the barrel flats, The "Made in Prussia" and the spelling of the word "Son" defines this piece as destined for United States/N.America export. (The single large Crown shown on the barrel flats is also somewhat characteristic of Sauer export guns bound for the U.S./North American Market) It would be interesting to See if Griffen and Howe has this Sauer S/N in their record books and what their record might show about the order. Another Sauer mystery likely never to be solved. Jeff
