Military patches for sale line one of the display walls at Homer Helter's Military Relics Store. Though Helter specializes in World War II items, he also stocks modern-day patches and uniforms, as well as knives and T-shirts. When he first opened about 10 years ago, people told Helter it wouldn't work. "They said, 'It'll never work in Naples,'" he remembers. In September, Helter plans to expand again, adding an entire wing of military surplus items.
