June 12, 2006. Stripped down view of drop bottom gon 724. Will Diehl and Bob Reib remove the old wood and rusted bolts from the mainframe. Note the "C-NM" stenciled on the end of the car. This stencil was applied in 1970 by the D&RGW to indicate that it was one of the cars sold to the states of Colorado and New Mexico. Photo by Marty Gonzales.
