It is a little more complicated as the brake filament is what is controlled by the turn signal circuit. Essentially the brake circuit is interrupted by the turn signal switch sending the desired side through a flasher to blink the brake filament. There were some turn switches designed to do this, not sure if they are available for your column (or at all anymore). However, a electronic circuit could be designed to do this with your existing switches.
36 sedan, correct me if I'm wrong, but if I have a functioning tail & brake light circuit (think 1157 bulbs, one filament tail, one filament brake), and I take a pair of single filament bulbs (1156 style) and wire them in parallel with my existing L & R brake light filaments won't the single filaments light with the brakes, but not the tail lights? I think that's what Jim is talking about, a two piece center light that acts with both brake & turns, one side flashing with turns, both sides with brakes.
Now maybe I misunderstood and it's a single bulb in the center light. If so, then it's gonna be a bit more of an issue, and there's gonna be some "interesting" circuitry involved (or re-working the light to have two bulbs, which would be my approach....).
