The big pushy-thing at the top is the horn button, and the pully-thing is the choke cable. Mervyn Rutter supplied me with a full set about 12 years ago when I restored my similar 1964 +4, and as far as I'm aware, still has everything. He also rebuilt my speedometer when it gave up a few years later. Never cheap, but always reliable and excellent service. Good luck; lovely car!
