Thanks for the reference.
I should explain that I named the tower "DJ" in honor of Don Jones who gave me the unique tower at the December TCA show here in Raleigh thamk me for taking the post of TCA Secretary of our Southeastern TCA chapter . You may know Don. He posts regularly and often has items to sell on the Forum from his large layout.
But nobody at that show or anyone who has seen it can tell us who manufactured the model!
