S scale 1:64 - its the perfect size and delightfully idiosyncratic! Cambrian, light railways, industrial, narrow gauge and American shortlines. Also 1:152 2mm Finescale and 2mmNG, and some overseas modelling in 1:160 N scale.
Indeed. As well as the S scale goodies, Jerry and Kim are taking 2mmFS 'Tucking Mill' (its 1st dry run before Warley, I believe), and that nice N-gauge 'Bodmin' layout will be there too. Bad planning, Mr.L? It's catastrophic!! :'(
