...and then we have the longarms of the Allied Powers!
Up first is a Spanish M1893 Mauser, which is cool and all, except that Spain didn't participate in the '14-'18 festivities on either side.
Next up is a Dutch M1871/88 Beaumont-Vitali labeled as a Belgian M77(?).
Then we have a Swiss Gew. 78 Vetterli, another heretofore unknown ally in the fight against the Kaiser.
Below that is a rifle labeled as a British Enfield, although it is actually an American-made "Enfield", probably by Remington.
The bottom piece is labeled as a "US Remington 1917 Rifle". While it certainly was built by Remington in the United States in 1917, it is a Russian M1891 Mosin-Nagant, intended for the Czar's armies fighting the Boche. Several technical problems interfered with delivery, however, such as Russia not paying, then chickening out of the war, then falling to fighting amongst themselves in November of that year. Pretty much the only Remington-built Mosins to ever see Mother Russia arrived there postwar in the hands of US doughboys who used them to shoot at Bolsheviks (which is a fine and good thing to do with a rifle.)
Also, apparently it enhances the exhibit if every rifle's rear sight, whether ladder or tangent, is set vertically, never mind whether or not it is actually intended to be used in that position.
