I may--just MAY--have a Peabody Coal set (locomotive and ore cars, still sealed in box), but won't be able to check and confirm until this coming weekend. I have a fair number of K-Line Plymouths that are still new-in-box and need to sort through (and eventually sell) most of them.
I'll contact you via e-mail this weekend if you don't find what you're looking for before then.
