Hmmm. The only photo I can find of 48142 at about the right period, shows that there wasn't a plate fitted to the RH frame. Although it looks like there's a trace of where one used to be. There's an electrification flash fitted partly over where it would have been. My assumption is that there's a plate fitted on the LH frame, although that's not visible in the photo. I note that the next Irwell 'Book of the 8F' is out now, and it does cover 8142. I put the book on my list to Santa, and I have been quite good, so maybe more info will be forthcoming. I mean, how do you get eight reindeer and a high cube sleigh onto this roof? And some of the old tiles are quite fragile... Whereas Gresley chose some excellent racehorse names for his pacifics, Santa seems not to have given it much thought when he was handing out names for reindeer. I suppose 'Comet' wasn't so bad - 45735.
