Is it possible this is the layout now preserved at 'The Works' at the NRM? I cannot find any information about it in any of my NRM brochures, but I think it was ex-Lancashire and Yorkshire railway at Horwich - so it would have eventually become LMS and then the LMR of BR. They served Rhyl, so it's not impossible it could have been shown there. Perhaps you could try www.nrm.org.uk and see if they have any more info.
If the NRM inquiries don't bring up anything let me know - I may be able to find out something from some signalling sources I have contact with.
