@ Fig, I wish I could have seen it up close like you did just to take in all the details...
At the risk of sounding negative, and believe me im not being negative at all, there are one or 2 things that will put this car into the top top resto leagues:
I mention this, not trying to detract anything from this super star of a car

, but rather as something of a yard stick if that makes sense.
1) The already mentioned steering wheel not being original
2) The dual post antenna being incorrect. This one should have had a centre mount windscreen antenna, either by Hirschmann, Bosch or Telefunken. Will have to check on this one...
3) The body beadings should be the Grooved type... similar to the groove or hump found on the winder and door handles. These ones looks like either German or Stainless Steel ones.
4) Fig, could you tell if the wheels were the correct 16 inch ones, as I cant make out to clearly, but looks like 15 inch ones to me. A well informed friend of mine shares the same sentiments
5) the missing wipers... Im sure they are still being sourced... probably OG SWF articles...
