Here is a sharp looking Wico 4 cylinder clockwise base mount magneto with a 35 degree ignition lag that may be used by many antique tractors as the case C, D, Early Continental engines as the S10, International McCormick Deering 1020, F12 .., some early Wisconsin engines and likely many others. Check your parts book to be sure or ask and we will research the application. Would make a great spare during showtime. Has been completely disassembled, washed, new front ball bearing, has new coil, condenser, rotor, dust seal, gasket ,and timing window. Components tested to factory specifications and replaced as necessary.Cap looks great and is clean inside. This is a modern serviceable magneto. Was professionally bench tested, good and hot as it should be. Will ship to US addresses, payment due in 5 days. If any questions, please ask! Thanks for looking!
