Boy Scouts of America (BSA) leader's whistle. Nickel over brass with original finger ring and lanyard clip. This is a true "oldie" as indicated by its weight and style (including the fitting on back for the finger ring). The condition is very good, showing normal use wear and age patina; nice clear insignia / mark; fully functional.
More photos gladly and questions always welcome.
Shipping is via USPS standard mail service. Priority service available (see options under shipping). Thank you.
