Product Details
Signal whistles, such as our large horn whistle, were an indispensable item on the early frontier, used primarily to signal light infantry companies with their high-pitched sound. They were also used by civilians, ranger companies and others. Ours are patterned after period examples. Both the single and two-tone models include holes for a lanyard.
