Still waiting to hear from Amati about the missing L-profile, I am continuing with other areas. 2 bumpers have to be bent 30 degrees.  In this post I will appraise DSPIAE Photo Etch Bender: Highly recommended. Figure 21:   Now some explanations on the next photos (Figures 21 to 27):   I am not too much familiar with railway terminology, the next component is called "Leaf springs". There will be 2 of them to be installed on either end.  Dry fit the parts
