@VI K Dag'gum! That is so very nice! You are a craftsman. Thank you for sharing photos and video of your locomotive...
Hello Sven, My name is Alan Lautenslager. I am located in the USA. I find myself going back to your postings for your wonderful C-25 Nn3. I am modeling Nn3 or should I say trying too! Is it possible to obtain the etching you have created and perhaps any STL files? I do have a couple of 3D printers both FDM and Resin type I have learned to use. I am 75 years old and retired so this project would be for my own use and not to give to others. I think I could adapt a Marklin mechanism to it. Thank you for the postings you made on what I call a true Masterpiece. You must be proud! Regards Alan
