In American Flyer's unusual numbering format, 427 is a combination of a 425 loco and 426 tender. The 426 tender looks so out of place behind this nice locomotive. It looks like a silly afterthought. The one in the Schuweiler book has black trim, mine has copper. Both are correct. I actually like the black trim better.
This common 421 tender would have looked so much better.
