Do you guys know what is the purpose of the turning wheel which is found in backyard area where the Rune and Overseer's music box is located ? It can be found on Safety cabinet and the key for the safety cabinet is inside a glass bottle you can find Galvani's Blueprints in there. So what is the purpose of that valve and where should it be used? I assume it is a key which leads somewhere, the letter reads that it is used to open the valve of pipe, it must be used somewhere where near Samuel's boat.
