Original horns for XK's?

[Rob_Reilly]

My 120 horns play E flat and G, a major third. They are also slightly sharp.
Maybe they need a tune up?

We discussed horns in May 2011.

[xk] Horns

The concourse judge told me that I should have had two horns sounding and he could only hear one. Either a high or a low note was out of order. Is there supposed to be two horns on a 1954 120 DHC? Town and country or two horns blowing at the same time ? or just one horn with dual trumpits? E.W. Blake
