It is also possible that that Engine did not come with the Car. The pictures in my book are from 190Ds. Did 190Ds have power brakes?

I mentioned this in a post recently - there's no way to have high vacuum in a diesel and have it still have enough air to compress to run - if there was we wouldn't need VPs in the first place.
I do suspect either the engine was one which never came with a VP originally or the timing device.
You have a good point. After an extensive google search I can't find any references for a 1966 W110 200D having a brake booster. There is the possibility one was swapped in?
