Thanks for the background information Kevin, Owen, me too had an experience driving on the footplate of steamlocomotives, back in the 70-ties in Germany, it probably the reason I'm still interested in modeling one
Here's an update; the chassis of the boiler; The model is very detailed, and it takes a little different approach than normal paper models, I paint the parts, the edges and the lasercutsparts with an acrylic , later on I want it to give the model a weathered look
