William,
Nice models!!
As a sidelight, it is interesting to see a model of flatcar 6200. I worked with Greg Coit on refurbishing that car for MOW service in 2018. Also, if you saw the recent thread and link to the current issue of Friends Dispatch, that's me with my butt toward the camera linseed oiling a sill for 6214. We expect to have it ready for MOW service this May.
Your model of 6219 is in much better shape than the original; it's sitting on the storage track in Antonito and it is in need of a lot of TLC.
