I took my 1916 Springsharp Plan presented in this discussion and modified it based on the above link information. It was tricky and I can't say it was entirely accurate. In reality, detailed plans were never created so we are just guessing. I used this site for information. weaponsandwarfare.com/2021/01/05/the-planned-refit-for-hms-hood/
