I've had this pair for awhile now and was glad that I didn't let the yellow green one go in a trade recently after I noticed the PG listing for a yellow green [040] Canadian Pacific. Even though I would not call this "dark" like the book lists, I am most sure it is yellow green nonetheless. I have paired it with a lime green Can Pac for comparison. Are there any CanPac experts who have handled these elusive [040]s before who could help me with identifying this piece? Thanks in advance for the help!
