This is another of the very popular miniature pickelhauben. This example is made of a silver-toned metal. It is not a typical metal helmet (not designed for a küraßier, GdC, etc.). The detail is good enough to reveal it is an American spiked helmet. It measures 2″ x 1 1/4″ x 1 3/8.” Along with the silver-toned exterior comes a gilt-toned wappen, cruciform, and spike. [Initially I identified this as a Prussian pickelhaube. One of my favorite people in the world (and a sharp-eyed bugger to boot) advised me that I had erred describing it. He told me it was in fact a pickelhaube from the United States! I pulled it back out, and had a look. He is 100% correct. The cruciform is different, as is the eagle, of course. The latter is vastly different from those that appear on Prussian pickelhauben. In the last quarter of the 19th Century pickelhauben became very popular with the armies of the world. This was also true here in the U.S. where our army also adopted the pickelhaube. Thanks for clearing up the confusion, Roberto]!
