A set of four 21t BR diagram 1/110 mineral wagons, based on the single wagon models of the same diagram but without the tracing on the underside to locate the Parkside Dundas 12' wb chassis kit. There is one of each end door type, and two with their end doors left out for you to fit with one of the four loose "spares". The two end doors which are left over can be swapped into other kits of course. Frosted ultra detail and frosted extreme detail plastics need thorough cleaning before they will stay attached to glue, and a good bond will be helped by the paint you apply over it later. Careless handling may always knock the door off though, and I suggest cutting out all the temporary supports from inside the wagon first. I do not know if loading with "loose coal" will work for the glued-door wagons, or spill out onto the track after a clunky rail joint or rough shunt (collision)! I will update this comment with my own experience once I have tried it.
