A set of 6v Bosch fanfare horns in used condition. I tested the horns with my car charger and both do work a bit but not as they should. They are not very noisy and also my car charger gave up at some point which means you need to check inside. The horns can be opened and normally they can be fixed. One horn is without dents but has a deep scratch. The other horn has a dent at the side. Both chrome gutters are not too bad but one has a small dent. At the rear side are screw terminal connectors. One fanfare horn is stamped with “HO / ESA 6B5” and the other with “HO / ESA 6B6” for low and high tone. Both are made by BOSCH GERMANY IMPORTE D ALLEMAGNE. The horns are together 3660g heavy, the diameter is 12 cm and they are about 10 cm height. The last three pictures are from Bosch VW parts catalog 1956 and they show the mounting options at VW Beetle.
