| Per the Delco-Remy history website, Delco-Remy got into the horn business in 1924 with the purchase of the Klaxon Horn Company in Newark, NJ. ((http://www.delcoremyhistory.com/Products/horns.htm)) It had been determined that Remy could build the horn at a lower cost than Klaxon and the manufacturing equipment was moved from New York to the third floor of Plant One, where horn manufacture remained until 1946 when it moved to Plant 7. The manufacture of horns remained there until it moved to Plant 10 in the 1980's. This was its last location until the product line was sold in the late 1990's. \\ | Per the Delco-Remy history website, Delco-Remy got into the horn business in 1924 with the purchase of the Klaxon Horn Company in Newark, NJ.
