I have always been curious what range of spark plug burn marks show... see above link for a good reference.
Hope this help others out. (wait for pictures to show up... it took a few seconds on my pc)

good find just wonder how old it is. Havent seen that shade of brown shown as being the teh best since they stopped doing leaded petrol, now you get a more grey colour on unleaded, this is another good page on spark plug colour.
