For your consideration at unreserved auction is this small antique Boxco Siren. It measures 5 1/4" tall and 5 1/4" in diameter across the top. This one is being offered as found, dirty and untested although it does spin freely. It is marked 6-8 volt, and I don't have anything with that output to test it. There is also damage around one of the mounting holes. No need to bore you with the details. A quick Google search will bring you up to speed as to the early history and rarity of anything from this shop. Please study the photos and ask any questions you may have. Quoted shipping is to the lower 48 states and includes insurance. Thanks.
