I have some nice dual plug David Clark's for airplanes. These are in excellent condition for looks and function. H10-60's, H10-13S and H20-10. $200 each n2450y@gmail.com
I am out of the 13S. I have 1 H10-60 now. I sell 5-10 a week at $200 so that is the going price. If you fly to Brenham and pick one up cash I may cut you a little slack. Maybe $180 if you buy me lunch. LOL!
