Hi PD's....& thanks Excelsior... the link to 'View of SW Captain Stuarts engine room from the ladder' is very interesting....PRG 1258/1/472
We can see to the right [STDB] a twin cylinder horizontal engine, however to the left [PORT] we see a smaller bore size [assumed as a twin cylinder horizontal] engine which appears to be mechanically linked back to the main engine :?: or it could be simply a horizontal interconnecting steam line [without lagging] :?:
Other pictures called 'the engine room' are I believe steam driven water pumps
