I can't comment on any of the smaller scales but in 7mm there seems to be those who are happy to play with what ever is thrown at them in the RTR market whilst others pursue a particular railway company and build or have built the specific stock they need which will not be found or probably never will be produced by rtr companies, some of whom have only heard of the GWR or BR diesel era.
Laurie Griffin has been supply castings etc. for decades and I can imagine that he wants to retire and good luck to him, we just hope that some one else takes the company on, there is still a lot of us out here that want to build models and don't want to un pack a box containing a jelly mould model from China, I did that in the 60's with Triang and like to feel I've progressed since then !
