The Ledge wagon has a narrow base with upright sides. But from a point about 18in from the floor the body is built out on ledges over the wheels to width similar to that of the Reading . The ledges are reinforced by scrolling brass supports which rest on projecting
cross-beams at the floor level. The match-boarding of the side walls projects front and back and is cut to form the porch-brackets which are decorated with pieces of carving, and are usually gilded.
The usual body length is 9 ½ to 10ft long. The size of porches and footboard is similar to that of a Reading . The floor or bed has a width of 4ft 2in to 4ft 6in, with walls below the ledges usually vertical, but occasionally with an outward slope matching that above the ledge. The walls below the ledge are 18in high and the ledges built out 8in over the wheels. The under works are similar in proportion to those of a Reading. The large hind wheels measure about 4ft 8in. The weight of a 10ft Ledge was between 2800 to 3100 pounds, although the 10ft 6in Dunton Ledge could weigh up to 3360 pounds.
