Thanks; good to see. I ordered it yesterday, with R40159, based on the information Hornby had given to @adamvb earlier in the thread and with fingers crossed. Two more standard class Intercity ones to come and then looks like just the two first class coaches to wait for in a future run with different number (and no fictitious roof vents).
Overall very pleased with these coaches and, as the poster above says, for a reasonable £40 with shop discount.
