Which horn is high and which is low?

[Bolt-Action]

Hey guys, need your expertise again.
my 55 special was equipped with a high and a low horn, but one is missing and I'm trying to figure out which one is gone.
theres a horn on the passenger side radiator support/core support, but on the drivers side the bolts, bracket and wire are there but no horn.
So was the high or low horn on the drivers side?
thanks again guys

Look very closely at the remaining horn. It just may have an "H" or "L" on it.

Great idea, thanks.
I'm not seeing any markings on it as its mounted, I'll pull it and see if there are any on the back side.
i noticed your sig, have you got a website? Interested in some nailhead roller rockers and mini starter.
