I'm not suprised, the local dealer told me that my '59 W128 sedan didn't exist so I could'nt order a fuel filter for it even though it was parked 20 feet from the parts counter. I even had the chassis number, what I did was order a filter for some kind of rare injected Porsche the the local import parts guru was sure would fit. And it did.
From what I know, the keys ordered at the dealer are cut in texas by vin number. It's not a strech to imagine the the correct key code is somewhere in the archiver, as I'm sure you know that MB keeps very good records. Another dealer was able to order a cut ignition key for my W128 sedan, even though it was a euro delivery car sold to a american serviceman stationed in Germany in 1959. Now, this is anecdotal information from the mid '80s when I bought it. I couple of months ago I asked the local dealer about getting a front oil seal for the motor and they refused to help and refered me to the Classic Center. Even though I had the part number from the dealer parts book.
