Also for persons from Europe where they slashed the numeral 7 to distinguish it from a numeral 1 that commonly had an initial small upward stroke at the top when hand written.

Not just a small initial upward stroke on the "1", but in some European
countries (I'm thinking of Germany and the Netherlands), some make that
stroke at least half the height of the number, if not more.  I have no
idea where the long top stroke originated.
