I am suggesting you to watch an interesting Video of http://www.piezosource.com/  which in nowadays it does production of Motorola horns.

I have a nice genuine pair of Motorola Horns since 90s, and I did not use them much, because I stopped exploring possibilities of DIY speakers sooner than expected.  :)



Speaking of electrical specifications,  there was a number behind the horn this is D 047, I thought that this is some product code, but Google search did not help any.
When I measured the external diameter of coil (plastic body) this measured 47mm Metric.  ;)

I did contact https://www.facebook.com/piezosourceinc/  if they have to deliver to me more information's,  I will share it here.
