    Period Reference information regarding Bosch Sportfanfaren for those interested...

    I have read the various threads on horns for model Year 1972 and model year 1973.

    Thought this information might be useful and of interest, because it is period Bosch and a couple of other Porsche information sources from 1972/3 that I have among my papers. I ran across this stuff when doing some tidying of my parts and literature.

    These are my two spare sets of nos boxed with papers and tags 12v Sport Fanfaren Name:  image.jpg

    The main functional difference being one set is 0321 023 908 "ohne" relais and the other is 0 321 023 910 "mit" Relais; I don't have the third boxed set variant but as the wiring is in the car I'm not fretting.

    These Sport Fanfaren horn-sets of this exact type are included in the the following Bosch All-service programm pocketbook for the period 1972/3 (print dated 10.72 which is coincidentally roughly the time of the 911 model year 1973 production would be getting going strong after the MY changes).

    My own British market car was in production in late 72 but it is definitely model year 73. (The called 73.5 variant popular in USA was not here in UK or in number of other country-markets for that matter -- although they have and do still get imported here)

    Additionally, I have a much more detailed Handlesliste a German Bosch publication for 1972- this is a fairly comprehensive catalogue covering a wide variety of Bosch automotive produscts running to circa 100 pages (it is print dated 4.72)

    This 4/72 date coincides with (the small reference date that printed in the white box but not readable in photo) of the large format Bosch advert that appeared for the same type of Sport Fanfaren in both my English and German Christophorus no 102 December 1972 and no 119 November 1972 respectively (this was the well known issue/s featuring the then new early series RS on the cover).

    The more detailed of these two Bosch catalogues gives more specific information on the Sport Fanfaren horn sets including their marque/ model fitment - a list that includes the 911.

    Also it provides details of the actual items that make up the boxed package shown above including the product number for each of the two horns along with the Hz and V (and other the relay etc if applicable)...number matches from table corresponds to the numbers stamped on trumpets both my nos sets pictured above)

    For interest, I cross referenced this to my original model year 72/3 Porsche maroon parts books - particularly the edition dated 9.1972 rather than the later printings of the same. The illustration shown diagrammatically (item 60) in photo below corresponds to the horn in the Bosch publication illustration in third image above. Publication from Bosch with the Sport Fanfaren is evidently a contemporary of that edition of the 72/3 Porsche parts book given the printing date reference 10.72 - as shown in margin small print in picture at bottom of this post).

    (For simplicity I will leave aside that uniquely cars for Swiss-market apparently had a unique horn specified in this Porsche spare parts book)

    I hope that going back to original 1972/73 documents from both Porsche and their actual component supplier Bosch's own product 72/3 information sources, (all date marked and from the period in question), is of interest regarding the Fanfaren horns that the equipment supplier was producing and selling around that particular time. Such items seem quite scarce if in NOS condition and apparently can command high asking prices these days.

    My horns and papers shown here are not for sale - this is posted just for information of interested forum members.

    (This post does not really belong in the Essex UK section but that is apparently the only place I can create a new thread in this forum I think?)

    In addition to the December 1972 English edition with new RS on the cover, this advert featuring the so called Banjo or Waffle style Bosch Sport Fanfares also appeared in August 1969 Christophorus English edition. Product might appear in other editions of the publication, but just tripped over it in this edition when looking for an article on another topic so I've added it here in case of interest to owners of cars from 69/70.
