Sorry, don't have a picture but if this is not answered, I might do just that.
There is a tiny pin on the bottom of the Canon FD lens mount. I am not talking about the larger pin, near the top point where the lens is engaged onto the camera and thus allows the breech mount ring to turn, but, instead, a tiny pin that probably measures only about 1/3 mm in diameter.
What is its purpose as, even without it, the lens functions normally? - David Lyga
