I went to Globe Militaria in the early seventies, must have been 1971 or 2. They were in Manhattan on West 29th Street pretty close to the river. 2nd floor of a warehouse, pretty sketchy. There were display cases filled with all sorts of WW2 German stuff, field gear etc. While I was there they received a delivery, which they opened on the spot. A couple of Waffen SS dot pattern panzer jackets, loaded with insignia. Even in my youthful naivete, I assumed they were fakes. But in the middle of the room was a round display case 5 or 6 feet tall with a dozen or so spiked helmets, just breathtaking. All high end, beautiful shape, plumes, officers helmets, etc.. Pretty heady stuff for a 15 year old. I could tell they were way above my price range (25 bucks) so I didn't bother to ask prices. That memory has always stayed with me.
