Feel free to check for yourself
1. Note how grilles on roof extend into bodyside where electric flash sticker is, not on model.
2. Note how front window and side windows start and end at same height, again not on the model.
3. Also, notice height of roof above cab in relation to cab window height. The MSTS version you show, roof height and cab window height are equal, in real life, the roof height is smaller.
Hope this helps.
