Here are a couple of items I need help with to put some finishing touches to the book about D&RGW 315.
1. I have a set of photos showing both sides of each of the sister engines except 320. I have photos of the right side and of it wrecked from James Ehernberger and CRRM, but have been unable to find any photo of the LEFT side of 320. Can anyone help?
2. Using Grandt's two books on locomotive pictorials and a handful of photos from CRRM acquired to create a set of L and R photos of the C-18s, I examined them carefully to create a table of changes in features over their years on D&RGW and between them. The table is attached. I would appreciate people reviewing and seeing what else can added to improve the table. We have about a month, maybe slightly longer to polish the table before it needs to be locked up for the printer.
