These whistles were commonly used by traffic police and crossing guards to direct traffic before the widespread use of electronic signals. The whistle is made of metal and has a loop for attaching a lanyard, which is included. The inscription "TRAFFIC SPECIAL" is stamped on the whistle, as is Made in Germany.
