Looking back at GWR parcels stock - Part 2. (No. 30, April 2001). There's an Interesting photo of W314W, a Hawksworth full brake in lined maroon. (quote)
Ah, yes, a feature by my good friend John Senior, of Mopok kits. By curious coincidence, I plunged into a crate of stored material yesterday and cam up with two printed sheets of Mopok Hawksworth sides. There's three vehicles in GWR livery and a full brake in BR blue, so Mopok didn't shrink from putting Hawksworths in GWR livery. My quest was for the instructions from their Dynamometer Car kit (which I found). That and the slip coach will enable me to have two Hawksworths in Western Region brown and cream. Incidentally, one of the slips lasted long enough to get lined maroon livery, and it ran in ordinary service after slipping had ceased. Two slips, one maroon the other brown and cream, were used out of Taunton on the Chard line, along with other Hawksworths and Colletts.
