Here's the little set I picked up recently, with Bruce's key completing the set.
The livestock and gondola do not say Overland on them - just "Peerless Stock Car" and "Sand and Gravel"; are they Hafner?
No markings of any kind on the tender, and it's a different color than the loco. Would the set have come like that? Also, no couplers on the caboose, so I need to look for one. They look like Joyline couplers!
