Not that they are not there, but I do not see any in this particular pic.

I do see some grey (300hz ?) horns x2, and some white (816?) cabs mounted above them.

Nominally in the upper corners of each side (one set just beyond, but at the same height as the lower stripes on the large US flag shown at the right)
