I have the very center section / lucite emblem, but not the entire horn cap assembly...I had bought a leather steering wheel from a 20th anniversary Toro some years back, and changed out the emblem since the car I was putting it in was an 88Royale FE3 coupe.
Anyway, here's the center emblem:
Its in real nice shape. If you can use it, send me your name and address and I'll send to you for nuttin'.

The rest of the horn cap can often be found for sale on Ebay:
