When I lived in Coventry my local model shop was Modellers World. It was owned by Barry Jones and yes he did produce some etched L.N.W.R coaching stock.
There were some 6 wheeled coaches. Some short bogie stock,a dining car 12 wheeler.
He was also working on the royal train stock. If my memory serves me right there were also a couple of vans ( bicycle van?)
What happened to the art work and who bought the range I have no idea.
A certain Mr Pete Waterman was a regular in the shop on a Saturday along with Ralph Jackson of Jackson Evans nameplates,Mr Shaw of Shawplan.
It was a great place to meet and chat on a Saturday. Loads of bits and pieces,kits and rtr to buy.
Brings back great memories.
All the best Steve
