[NSRCA-discussion] Control Horn Mounting

[Chris]

HI Tim,

We will have the CA Model horns (Hyde)  in a week or so.  I don't have 
the prices yet so they are not listed.  I am also working on getting 
some other aluminum horns like the ZN Lines ones.  The ZN ones are like 
$9 each as as you can imagine, I won't be importing those.  These other 
options are high on my list and I should have some details within 2 weeks.
