well done Paul, great catch.
You have got the 'HAZET' kit which is doubly desireable as early Porsche owners will drool and covet over it as well as well as volkswagen victims.
check this:

But please... make it a hobby to restore it, and tracking down the original parts will be an adventure in itself, they arent necessarily expensive, you just need to be patient.
Unfortunately there are people who will buy these tool kits and then systematically canibalise them by selling off the parts one by one on evil-bay to make a profit. I can understand the temptation to do that but each kit is unique for its year and it just results in everyone having mismatched sets and one less correctly matched set.
