Thanks for the information on this forum. I'm a model engineer from the Netherlands and currently building a Y14/J15, although on a bigger scale (1:11.3, 5-inch gauge). For me, it is difficult to get good information about the loco, but I visited the North Norfolk railway in 2022. This post is however very useful, and I'm always grateful for any other info about this loco. Kind regards, Erik-Jan Stroetinga.Richard,
As Tony says the cab roof is much as the original when first built, judging by the photo's in Yeadon's book it seems that they did not have rain strips in the early days but gained them in later GER days before the LNER.
Some details in the attached pdf's show early roofs had a strip or band over the top also check out detail no.28 in the Loco Details file.
Once again try and find photographic evidence of your particular loco.
Col.
