thanks for the reply. i now know more about this ship than i planned. your pe set looks like it's for the 3 corps which as the extended off the side and stern angular flight deck, there is a set for corps 2 which has a rounded flight deck the size of the stern. both are flush decked.
i have a 1 corps which has an elevated forecastle dropping down one deck to the forward cargo deck. i may just get some generic railings and helo platform netting. that's all i was really interested in. doesn't have any planes so don't need that.
it's rather far down the list of builds so i will keep looking. i think they did a pe set but appears to be discontinued.
