Pictured above are a pair of NOS Ford A-12300 ignition condensers. These have the Ford script and the zinc can.
Pictured below is a 1928 letter from Ford in reply to a reporter's question about the rating of the condenser. According to Ford, the capacitance is 0.3 microfarads.
Also noted is that the ignition coil has 250 turns of #20 enameled wire in 4 layers in the Primary, and that the Secondary has 16,000 turns of #38 enameled wire.
