Have a look at this link:
Should explain all.
First three letter of chassis and engine numbers indicate basic model - W107
for chassis and M117 for engine.
David - BTW, you might want to check that engine number - I looked in my
shop manual and it says that engine for the 73 SLC should be M117.982 and
chassis W107.024. No engine with 117.988 is mentioned.
OK - I now see from quoted message that David is in Australia. But, I think
my shop manual covers all cars and no mention of a 117.988. But possible
that a small change for Australia might be why last digit is different?
Yes the car is in Australia
I will check that engine number.
The car does not carry an Australian compliance plate
from which one canclude that it was possibly a
grey import into Australia.
Being RHD if it was not originaly delivered to Australia
it may have come from South Africa, UK, NZ, or some
SE Asian countries.
Many thanks to all who contributed
my interest in this vehicle is being greatly stimulated.
I have owned a '72 350SL, which has a similar 4.5L engine, for the past 16
years. Very solid engine although a bit temperamental - sometimes idles
unevenly and sometimes seems to get overly rich at low speed - It's one of
those things that I will have to learn more about, because few local
mechanics know about these older cars.
If you plan to drive the car regularly, be aware that they have terrible
fuel consumption. But still great fun.
I presume that
"Mich." that appears on the not very clear photostat that I have of the
after a word that may be "fabrikat" means that this car was built
