British Union of Fascists Cap Badge
The British Union of Fascists was a political movement, prominent in Britain in the mid-30’s. Basically your garden variety fascist rather than Nazi organisation, think Mussolini. The badge unfortunately is a complete crock, manufactured in England in the 60’s by by a firm called Dean & Adams. Note its marginal resemblance to a Polizei badge as well as its use of the late war SS skull. Those things by themselves should make it obvious that it’s a fake, given that the BUF was a proscribed organization in 1939.
