Thanks for the input. I’m planning to go with a three-vent setup for now. The images I’ve looked at do show something a bit unusual with the vents on the All-First carriages, but in the absence of any solid evidence to the contrary, I’m comfortable assuming the three-vent configuration was part of the rationalization process—based on established practice and experience with the longer carriages—when First Class was phased out. Feels like one for the “life’s too short” list! That said, if clear evidence of a retrofit ever turns up, swapping out a roof detail wouldn’t be a big deal. Pictures to follow in due course.

Hey all, Sorry if this is a bit of a beginner question or something that’s been asked before — I’ve had a look around but haven’t found a clear answer, so here goes. I’m trying to figure out how many torpedo vents were on the all-first coaches of the Clogher Valley Railway, and how they were spaced. The best photos I’ve come across are on pages 33, 89, and 151 of the Patterson edition of The Clogher Valley Railway. From what I can tell, it looks like there are five or maybe six vents — which is more than the all-thirds and the first/third composites (it seem to be weldocumented those had just three). Also, there seems to be an extra one mounted on a rectangular plinth above the balcony at one end — maybe even both ends? Would love to hear any thoughts or insights if anyone has looked into this before. Thanks!
