Condition report:
The item is in fair to good antique condition. There is significant surface oxidation, tarnish, and areas of verdigris on both the interior and exterior, typical for metal equipment used with corrosive photographic chemicals. The lid exhibits a heavy copper-coloured oxidation. The mechanical latch and screw-cap are functional. The internal rack shows surface wear but remains structurally sound with straight slots.
