[SEL] patent search

[39 Sedan]

Hi guys, In the past I have saw some of the U.S. patent searches you guy's have ran. I hope someone can help me with this one. I have a spark plug,no name on the insulator.It is a take apart plug .On the base the flats are stamped A.C. with a patent date of OCT 18,1899.I don't know which this could be a) "ALBERT CHAMPION COMPANY" Boston Mass,(1906-07) or B) Champion ignition co,Flint Mich,sometimes marked CICO or A.C. AFTER 1908.The time of the patent date 10/18/1899 Albert champion was working with Charles Metz for Waltham manufacturing in waltham Mass.The patent should be in Albert champion's name.I don't have the patent number.Can any one help?
