[SEL] patent search

[39 Sedan]

Thanks Tom,I am putting together a display.I have a 4cyl magneto that was 
marketed by the "Albert Champion Company" Boston Mass.(1906-07).That plug is 
one I want to fire with the mag.Each plug will mark a major event to the 
company.All are restored now I need to document each of them.I will try your 
method to find this patent. I know I will be on a fishing trip.Thanks 
again>>>>DALE MARK  FLINT MICH>>39sedan at sbcglobal.net
