" The 401 is he ultimate in toys for boys (and men too). The unit acts as the power plant for many Marklin erector constructions illustrated in the booklet that accompanies the model. The 401 is even fun by itself. Its an upright! Its a overtype! Its a traction engine! This set is complete, with all the ""bits and bobs"" collars shafts, screws etc. Even the single size spanner has the G.M.&Cie shield logo stamped into it. "
