The original design in 1964 of MGR hopper wagons included having an extension - the canopy or 'top skip' which permitted the wagons to carry 32 tonnes - so using the full 45t GLW then the highest weight permitted for a 2 axle wagon. Few colliery screens were high enough to permit their use and they largely remained in Scotland. Without photographs it is difficult to know which wagons had these and when - as they were removed and put on other wagons and published TOPS codes lists are misleading. Lots 3575 and 3647 appear to have all been built with them. Drawing and information were published in Monk-Steel, David., Bartlett, Paul W. and Mann, Trevor, (1986) BR Air braked Coal Hopper wagons. in Model Railway Constructor Annual 1987 pp 20 - 36 edited by Leigh, Chris. and in Monk-Steel, David (2011) Merry-go-round on the rails.
