I found an old Harley soft leather aviator or pilot's helmet in an old house the other day. It looks like it is from the 20's-30's. There is a label inside marked Harley Davidson Motorcycles-Clipper. The logo is bar and shield in orange and white and has wings behind the shield. Does anyone know when this logo came about? I have not been able to find anything like it online. Thanks for the help!~Todd
