Bump Keys correction

The statement,

"A little bit of history, the patent for a 'bump key' was first registered in 1928. Then in the 1970's concerns were raised as to the security issues posed by 'bump keys'."

isn't quite correct.

George John Baron applied for a British patent in July 1925, which was granted (#251,810) shortly thereafter. Then, on August 23, 1927, he was granted U. S. patent #1,639,919 for the same "Locksmith's instrument to open all standard makes of cylinder locks."
