I believe what you have is a 6 V horn. The plastic back was probably 
generic, made to work for whatever guts Hella stuffed into it. I 
suspect that the markings on the very back were stamped in later, so 
they indicate what you actually have: a low tone, 6 V horn.

I'd go ahead and try it on 6 V (actually 7 V.) If it doesn't work, 
you may need to dig open the adjusting screw and tweak it. Adjust for 
minimum current draw while still working reliably.
