The W5068 "Charringtons" 21 Ton Hopper Wagon is more commonly found in a Period 4 Long Box rather than this short box version. No other variations exist I believe other than the Long Box packaging of Period 4. Running number is B42181K. As for all Period 4 Wagons it has metal rimmed wheels and pin wheel axles.

Wagon and box are "near mint" for their age. This wagon came supplied with split yellow plastic, or, a yellow card bord insert.
