Understood on the application number... there is actually a good thread around here that documents all the application numbers.
But... there's always a but... I am trying to figure out the other numbers, i.e.
top left = part number
top right = material used
bottom right = application number
bottom middle = date code
What's the number between the date code and application number represent?
On the bottom left, other than the little Porsche symbol that has been cut down, what are the other two markings referencing (the ones in the circles)?
Thanks in advance.
