The old Revell Hope/Haven kits can be made into any of the C-4 variants. The most common ships to use that hull were the 'General' class troopships such as the General Brewster.
Navsource has a good pic of the original ship and the containership Philadelphia which she became.

I obtained a built-up kit of the Haven on eBay. After breaking it up and spraying it with oven cleaner, I cleaned up the decks. It will be waterlined. From here it's all scratch building. It looks like the hull is about a cm too wide for the length.
Not sure what vessel this will be. I have some barely legible copies of the profile plan of the General Brewster. More likely it will be the containership Anchorage.
