Very interesting, very convenient as I’ve just brought one to paint into UTA Green (not accurate I know, but certainly better than nothing) so the video guide will come in handy! Should that go well I might get some more to replicate or paint into CIÉ black and orange or green (also not perfect but it’ll suffice)
regarding the Clestory coach, I recon it could be modified to look like the BCDR railmotor in auto train condition, though I can’t imagine this process being particularly easy
