Hello all, I'd like to know more about the composition of the large cargo winches next to the holds on deck, particularly the steam-powered winches. Does anyone know if these were made of brass or bronze? What about the size (potential weight)? I figure there must be a contemporary advertisements somewhere that would mention their composition. I've looked through "The Shipbuilder" and tried a somewhat in-depth online search but have yet to arrive at an answer. This question is not really limited to Titanic specifically, but large liners built during the late 1800's/early 1900's in general. I know there is a wealth of knowledge on Titanic out there and figured this might be a good place to start. Thank you!
