mechanical part

  1. 2 cm Small 3 Pointed object, Shiny Copper/Brass center? To me it looks like something mechanical, maybe part of a tool or clock? Kind of corroded. Im sure the chances that someone recognizes such a small piece of something are slim but please, surprise me! I tried searching google and just cant find anything like it...
  2. Agricultural machine parts or tank?
