I wonder if in the original list, a '1' was misread as a '7' or vice versa. I am told that in some countries the '7' is conventionally written with a crossbar across the downstroke to avoid this. My father always did this, for all it is not common in England.
In Germany, we *always* write a bar across the 7. I don't like uncrossed sevens because they are ugly ;-) and hard to distinguish from a 1.
