This is a typical wagon of its day, provided with grease axle boxes, no automatic brake and a handbrake on one side only - an arrangement that increased the risk to shunting staff needing to apply the brake on a moving vehicle.
Since "either-side" handbrakes were made compulsory on the main network in 1911, this unmodified wagon must have left mainline service at an early date. It was acquired from the Royal Navy internal system at Bandeath.
