I thought I had been very diligent in the strip down of this car but as I was going through the last couple of boxes of nuts and bolts to send away for plating, and there are hundreds. I came across this part. There were a few bits laid in the glove compartment when I got the car and I think this may have been amongst them so it may not even be anything. Any ideas?
I bagged and labelled absolutely everything as it has come apart, I have taken over 1000 photos, really! since this project started and am surprised that I would have left something so odd looking unlabelled or with no picture, note, anything. It's about an inch across.
Someone put me out of my misery.
