Hi Ernie and welcome to the Phorum. Looking at the 38-12 schematic, it shows a diagram of the oscillator coil. There's an index notch on one end of the form that you can face toward you and down. The terminals will be at the top. Terminal one is above the index, terminal two is to the left, terminal three is on the right and terminal four is behind one. One connects to a 110pf cap, two is grounded, three connects to 6A7 grid 2 and four connects to B+. You may not need to rewind the transformer if you measure continuity between one to two (2.5 ohms), and three to four (3.5 ohms). Others will chime in with info on wire sizes. I'm thinking you may have to bake the form at 200 degrees a couple hours before rewinding.
