I've made a start on refurbishing the tower shown in an earlier picture. The main body of the upper turret level is made of foamcore, cut into equal rectangles, rabetted then glued using PVA. The cupola is cut from the thick inner card tube from a roll of labels, with thick card capping both ends. I want to cap the tower with an onion dome to follow the mitteleuropen Baroque style, but this poses the problem of how to approach it. A few ideas are bubbling away and I'll see which suits. I'm going to leave the cupola seperate to make it easier to model the dome then attach it to the turret and the whole to the main tower.
