Model of a Life-Saving Cart for Shipwrecks

Two identical models of rescue devices for shipwreck rescue operations on a beach, incomplete. Each device consists of two two-wheeled water carts coupled by beams; these carts are rotated ninety degrees around their axis so that the shafts point straight up. Low compartments are built around the carts, completely filled with empty barrels, and provided with seating and walking planks on top. Some barrels are missing. The wheels have adjustable blades between the spokes. The parts of the wagons are connected so they can be quickly disassembled. [combined description]
