Vintage Hawaii Sugar Cane Mill Processing Lot of 5 Photos

Lot of 5 vintage color photographs documenting a sugar cane processing mill, possibly in Hawaii (unconfirmed but visually consistent with Hawaiian plantation tourism sites of the era). Images include: interior view of large gears, conveyor belts, and pink-painted pipework machinery; exterior shot of the mill complex with a booth labeled 'INFORMATION,' smokestack, decorative lamp post with weather vane, and rail cart, suggesting a plantation visitor/tour site; close-up of freshly harvested cane stalks piled on a chained wooden cart at a loading dock; exterior conveyor feeding cane into the mill building with tropical foliage and fencing visible; and a faded shot of a flatbed rail car loaded with cut cane stalks near a roadside with palm trees. All prints are color, standard snapshot size, consistent with a personal travel/tour set. Condition varies: several photos show mild fading and color shift typical of the era; the rail car image is more significantly faded (quality noted as lower). No captions are visible on the fronts. Together these images form a small coherent narrative of a sugar mill tour or plantation visit, better sold as a themed lot than as single generic industrial scenics. Associated with the estate of USAF Col. Patricia Jane Harrington. Please review photos for condition.
