From the time I became obsessed with Napoleon I have wanted to own a Napoleonic-style bicorn. But I’ve never found a place that sells them – I mean, high quality ones, not the cheesy costume style.
In the comments section of an old post, Captain Flunky has pointed me to this site HatCrafters.com which seems to make a perfect replica (scroll down to the bottom of the page). The company is based in Philadelphia and their Web site is pretty old (Nicholas Stark – perhaps you can pay them a visit and see if they still exist!).
