Yes...again all very crisp Steve......we can see the lightly distressed rivet detail etc
Just one observation....a part of the Fireman's job in these craft to set the air intake scoops to maximize air movement and as such to lower the ambient air temperature in and around the boiler/engine space and commonly used in conjunction with an opened engine room skylight as the warm/hot air outlet
These air scoops [often called ventilators] are as distinct to air educators which drawer air out of enclosed spaces
So getting back to the Fireman's role...this was the setting the ventilators direction to capture the prevailing breeze......so setting both athwart ship is questionable
[don't be concerned about a visible turning mechanism for the ventilators, these were simple telescopic rods to hand or ratchet wheels to rotate the ventilators from the lower boiler room floor space at chest height...[the level was also called the boiler
flat]
