Specification of SA horns

Hi everyone, I found a bunch of SA horns in our laboratory. I heard that SA was bought out by MI years ago. The problem is that nobody has the specifications or datasheet for these SA horns and when I went to visit the MI site they don't have any information either.I typed in the horn model number in google and couldn't find anything useful either.

Does anyone know where I can more info about these horns?

SA 12A-18
SA 23-5.8/8
SA 23 2.6/8
SA 3.9/4&6
SA 5.8/4&6
SA 23-3.9/8
SA 23-1.1/8
SA 11-0.75
SA 12-0.5
SA 23-12/4
SA 23-1.7/8

Re-google it.

I've found: http://www.mi-technologies.com/catal...s/s23wfeed.pdf that describes them.
