Have always been a fan of the AT&SF and have owned more than a few of the their Warbonnet diesels since I was a kid. Was not aware that the prototype had the beautiful stainless panels until just a few years ago. Didn't know of any O scale plated units at the time when several years ago I came across these MTH beauties at a train show in HO. Now why couldn't Lionel have produced any like this?
