Here is a link that contains all the photo etch parts to replace all the cardboard wall sections in the Amati Kit. Plus a whole lot more to update different parts as well. There is one that i am very much looking forward to and it is this one below. The dome will look fantastic when it is built up. There are also etched lifeboat covers with the ropes and the extra lifeboat railings that were not included in the Amati kit. These is the options for the dome. You can use the 2 circular ones for both domes without modification. However the Oval dome is actually accurate for the forward Staircase, but you will need to modify the housing for it.
