Hi Mikkel, many thanks for your notes and the various photos and links, which are all very useful. I’ll start to rough out a plan based on what you have provided here and your original post. I’ll try to track down the Wild Swan book too, but if you do come across the plans or have a moment to share the basic measurements that would be very kind indeed. I very much admire your work, by the way, and your often very original posts. Jonathan
