About as much use as the ashtray on Kruse's Harley
I asked you the question, not the other way round.
You made a statement that such a thing is either an error or it is not, with no other choices.
So, again, which of the 9 would you regard as errors (lets say for the purpose of your catalog).
It seems that everyone has a different view of where to draw the line.
This was not supposed to be a trick question.
