Copper Spark Plug Washers

Does anyone have a photo of the copper washers that were used on spark plugs in the 60's?  Were they similar to the indexed copper washers that Jegs or Summit sell?  Do the copper washers seal better?  thanks

A bit pricey.

Thanks Kevin.  I wonder if there is any place you can just get the washers.  The 66 SS used a AC R43N plug.  Most recommend using a R43XLS or a R44XLS which is a little hotter.  And both put the tip of the plug further toward the center of  the cylinder, suppose to make it run better.  The AC R43N plugs are even more expensive.
