Sorry, Am I missing something here? What are the errors with whitewashed cattle wagons and black and white cows in the yard.
Maybe I can see that black and white cows are dairy cows and would only take the train for their final trip to the great pasture in the sky but I can't see the problem with the whitewashed cattle wagons. Nearly all pictures I've seen of cattle wagons in the pre-WWII era have whitewash splashed rather haphazardly on them.
