I was at our local Lincoln model railway club show this weekend and came across this guy;Severn Models, he produces some very useful model of garden sheds,lineside huts, workshop tools, and a Mackenzie & Holland Type 3 signalbox all photo etched,which I thought could look rather Irish if painted in the correct livery. The sample etchings on his stand were excellent; so I bought the signalbox kit. His website is http://www.SevernModels.com
Also http://www.petite-properties.com who do a very good range of buildings and their range of paint/colour for finishing looks very good. Usual disclaimer just a customer!
