When did Ford use glazed porcelains on the coil box and when did he use unglazed porcelains? I am working on a 1914 Ford and would like to use the correct ones.
Thank you, Craig
Fairly sure the glazed tubes were used up until the 1916 model year.
Checked up with Bruce's CD and Gail Rodda book to review, seems like the shiny glaze were used up to 1917 or so.... P/N T-5810, the Ford non-glaze Fac. No. 684 with the earlier smooth shiny glaze as Fac. No. 5005.
I like the glass ones.
