Universal Siren/For All Bikes

This auction is for a "Persons" Universal Siren. This item is NOS , it has never been used. My best guess as to age is late 50's or early 60's. The siren was manufactured by Persons-Majestic Mfg. Co. , Worcester, Mass. It is Model No. 150. The box states "for all bikes...Easy to attach....No battery required". The instructions on the box say it can be mounted on front or rear wheel. As you can see in the picture all mounting hardware is attached to the operating chain. The box does show wear and tear and some misfiguring as well as some staining. BRING BACK SOME MEMORIES???? Please email with questions. GOOD LUCK Bidding.
