While we have, indeed been spoilt with the Restriction 4 Maunsells - though 1934 & 1936* type are still absent - we have no RTR Restriction 0 or Restriction 1 coaches. Plenty of Bulleid designs are now available from the trade but not, yet anything like the full range. As for EMUs - hmmm - a service made up of 2BIL, 2HAL & 5BEL units is hardly prototypical ........ and the later, BR Mk1, units are well short of comprehensive coverage. ( Various Mk1 units could form the basis for types which ran on other regions, of course. )
* the Driving trailer Compo is a notable exception - but WHY has it never been released in original form ??!?
