FYI, Vol. II of ANTIQUE FIREARMS 1849-1899 is now available on Amazon. This is the volume from my anthology that has the story of the models 1866 and 1868 rifles which were assembled off-the-books at Springfield in 1871, as well as the overall total of Springfield Armory guns shipped to France for the Franco-Prussian War. Lots of other gun history as well.
