I do recall some older covered hopper cars with Wonder Bread scheme, but I thought those were special run: Either by NSE/NSC or by BLW or another company that produces low-volume custom painted runs of cars. Not MTL.
They were two different thoughts. I was pointing out that despite someone saying that MTL has had plenty of time to release the Wonder Bread or Brach's cars, but didn't they only recently release this body style?.
And yes, the wonder bread car was a special run, OLDER MODEL, not an MTL car.
