Hi, RioGrande. I'm been tempted by the Red Caboose' D&RGW GS Gondolas (I need put some to work hauling limestone from the "Glacier Gravel" mine!). They look very nice (in the RC website tiny pictures, though), but I don't know how prototypical they are. After checking the Eager's book the #s seem correct, but the RC pictures of them are too small to compare (you don't have them in yor list, either). Do you have some info about these cars?
