When I was a graduate student at the Albert-Ludwigs-Universität in Freiburg in 1969-70, I made friends with an antique dealer who had a stock of "Pickelhauben". I came home with three: a Bavarian infantry model, a Prussian artillery model (with a cannon ball in place of a spike) and a lobster tail all metal version, like the ones worn in that Swedish ceremony. I have never seen a modern day German soldier using the "Paradeschritt" (goose step), btw. Too identified with the Third Reich, I suppose.

As an officer on the staff of the Schools Demonstration Troops at the Marine Base at Quantico, I participated in a lot of parades, but none even remotely like that one. It was the only official use I ever had for my sword, however.
