Kèn hơi tàu hỏa phong cách steampunk

This is a prop which I created for my daughter. It is based off an old train whistle and has been designed to hold a compressor blow-off tool in the body. The whistle uses compressed air to create a train noise and is triggered when the handle is pulled downward. The whistle is comprised of five prints which are assembled using 3mm screws and 4.2 mm. knurled insert nuts.
