Hi or Low Horn?

[oscillon]

Hey All,

I have a missing horn on my 66 911 (right side). Is there a way I can tell if the missing horn is the high or low tone?

Once we figure it out I'll need the missing horn in case someone has one.

Cheers,
Dan

What frequency does the badge on the horn you have indicate?

901 635 102 00 . . . .911 coupe -68, low pitch 390Hz, only with
901 635 112 00 high pitch 520Hz
this pair only through chassis 301224

901 635 102 01 . . . .low pitch 290Hz, only with
901 635 112 01 high pitch 345HZ
this pair from 301224 through 305100 (start of '67MY)

Bringing back an old post here. My 66 #320397 appears to be missing one horn. Did all early Porsches come with two horns? Sorry, but I don't have my parts manual here at home to reference. The horn I have is very large, has a Bosch tag and is about the size of a small cantaloupe from memory. It's not here either or I would post more info. Thanks, Mark
