Vintage Chrome Star Ornament

These are marked 8-32. 

I'm not a motorcycle expert,  but   I did research these and they are described as a  part  for Harley /  Indian Motorcycle   I also saw "hot rod rat buck" in the descriptions 

From the end of the  point to the end of the opposite  point they measure about 4" (very slightly less) 

I don't know the age of these, but they have been stored for quite some time

They are in fairly good condition with a little aging and slight pitting - mainly on the edges. I wiped them off, but did not use any cleaner  on them. 

These will be mailed with insurance
