Vintage Porsche 356 Original Bosch Germany HO 37 H0/FSA 6/16 Horn.  Tested and worked a few years ago before putting the horn into storage.   One of the wires in the back came off while the piece was being stored.  I did not try to put it back on due to the horn being vintage and I am not certified to perform such a repair, therefore, whomever purchases will need to put that wire back in the correct slot.  This is not a set it is a single horn.  Sold "AS IS", therefore, please review the pictures in detail as this will be the actual item you will receive.  If you have any questions, please feel free to email me.  As always, thanks for visiting.
