How to identify High / Lo horns on early 76 280Z

[MattSaint]

Howdy,

The original owner of my 76 280Z replaced the drivers side horn with a Sears air-horn.  I'd picked up a few horns, before realizing there are differences (more so than just High and Low).  That being said I snagged a horn and bracket for an early 280Z while I was down in Carlisle PA at the show.  I got it home and started reading the past posts on horn identification.  I've been able to find information on how to identify a horn for a 240Z, but nothing for identifying ones for the 280Z.  Any help is appreciated.

Thanks!

These are a couple pictures of one from my 9/75 production 280Z

I will check my shop this weekend for any hi/lo markings.

I suspect the decibel rating is the clue...

Thank you Mark!  Currently all the ones I have say 115dB.

That came out great, did you use a sand/bead blaster on that?

Glass bead in my blasting cabinet. Super fine. Slow work but pretty.
