Every year again... H0, TT, N and Z scale figure Advent calendars The figure Advent calendar has a long tradition. For many years, model railway enthusiasts and diorama builders have been looking forward to a small model figure every day before Christmas. The figures in the calendars for the H0, TT and N gauges are hand-painted. The figures in the Z gauge calendar are 3D master figures, i.e. they are 3D printed in full colour. A figure Advent calendar is the ideal gift for every model railway enthusiast.
