Working from oldest to newest:
First up Dino Steering Wheel - I got this off a 914-4 PCA stock race car back in the early 90s. Could never get the racers tape off from wear a stop watch was mounted. This was before lap timers where affordable for the CSOB.
I used it for years in my 1974 914-4 Auto-X car, smaller than stock wheel.
Dino, hub adapter, horn button, cancelling ring, and some where I have the bag of Allen screws to mount it to the hub. $75 shipped - Sale Pending
