Thanks to the Railway Modellers Ireland Facebook group and Jonathan Beaumont in particular I have received the following information:
JB – Originally olive green – quite dark, and with lining. No actual details of the lining survive but perusal of early photos suggest black and white. The letters “S L N C R” were in shaded gold or yellow on the tank sides. It is not known what colour the nameplates were, though during the “black” era (probably about 1910/15 onwards) these were variously black with red writing, or red with polished writing.
MB – There is a photo of classmate “Lurganboy” on the smugmug website, with “SL&NCR” lettering on the tank sides, but the rest of the loco looks to be unlined. Would this lettering have been carried in the olive green days with the lining?
JB – Yes.
JB – After they started painting them unlined black I believe, but cannot be certain, that the lettering continued for a while (on the unlined black background). Connecting rods are often seen (copied) on models as red. Evidently they were not – they were black or more likely, unpainted.
This model has recently been stripped of it’s tired and chipped paintwork and is presently awaiting a repaint by John Cockcroft into fully lined LNER Darlington green livery. It will retain the same name, but will soon proudly carry new nameplates from Diane Carney.
It has recently transpired that Wally did actually build three finescale Tennants like this, as well as the scaleseven version shown elsewhere, so four it total. The recently discovered model was in fact sold by Wally himself in an unpainted condition and has since been painted in the livery shown above by Alan Brackenborough.
