Although these wagons are basically standard Lima, I have very fond memories of this type of wagon at my local station. During the eighties and right up to the end of Speedlink they used to arrive, either in a block train or as part of the Speedlink service. If on a Speedlink they could also have UKF wagons attached.
This is my block train of twelve wagons, although I would like to put together another service with some mixed wagons.
I did notice how variable the weathering on the wagons could be, I guess this depended on just how many East Anglia to Scotland trains they had run without cleaning. I tried to reproduce this in my Lima rake. This service was a trip service from Ipswich yard, having been trunked from Whitemoor.
Only my coupling modification has been done. I may well revisit some of the dirtier wagons and redo the weathering on the suspension.
