aargh! see what you mean...
The 1872 final was staged at the Kennington Oval (London). The following year it was played at Lillie Bridge (also in London). It returned to Kennington between 1874 and 1892.
"Football's rules were changing during this period. 11-a-side teams were introduced in 1841, the referee in 1845, the cross bar over the goal and the half time break in 1875, the throw-in replaced the kick-in (1877)."
