This is an interesting brown Bakelite and chrome pin! The style looks very Art Deco to me. The pin is unsigned but well constructed and the chrome and pin are securely attached. The chrome is in the shape of 3 circles and is very shiny. There is only one small section that has a little bit of a brown tinge to it (barely noticeable, see pics). The clasp is a C-clasp. Tested positive for Bakelite with Simichrome.
