Mystery Mercedes surely made for a maharaja?

Berlin, September/October 1921: “HIGHLY DECORATED: ONE OF THE SMARTEST CARS AT THE EXHIBITION. In spite of various cries of poverty, the Berlin Motor Show exhibited cars which were of a most expensive kind. The one above is decorated in relief, and its price is 350,000 marks.” (What’s that worth now, anyone?)

Don’t know who bought it but it was in London in December 1921 and not everyone’s cup of tea. The Tatler’s, J. A. Ashton, clearly venting post-WWI xenophobic, upper-class (please note, now 100-year old) British sentiments, wrote in his Petrol Vapours column:

"Jazz Bodies. The motor scribe in one of the “dailies," who wrote a lot about Jazz-bodies at Olympia, evidently without having been there at all, dropped a bad brick. We've much too much sense to go in for anything so putrid, except for racing jobs pure and simple, and that is something to be thankful for. On the other hand, the Boche simply loves the bizarre in carosserie, and never paints his cars less than about three colours, to say nothing of adopting the weirdest and most wonderful shapes. I guess the limit, however, was reached by a four-cylinder Knight-engined Mercedes which I saw in the West End just lately. It was exhibited, I'm told, at the Berlin Motor Show, where I'm sure all the Fritzes, and Hanses, and Berthas, big and little, fell down and worshipped it. As to the chassis, that's Merc, to the last rivet, and there's no more to be said. But the bodywork is an abomination before the Lord or before anyone else for that matter. It is made of polished metal, and the artist, unable to leave such an expanse alone, has engraved, etched, chased, or otherwise sunk into it, a hijjus [= hideous] decoration. "A pattern so gross that his soul sickened at the sight.” A pattern so florid, so nauseatingly North-German-Lloyd, so blatant, so meaningless, so tawdry that it would disgrace a bath room wall dado and that's saying a good bit. Ugh! How could they do these things? Jazz! Aren't you fed up with the beastly word? Some lunatic the other day was recommending that golf balls should be jazz-painted, and no doubt you heard about the johnny who tried to induce a hen to "sit" by painting her eggs with all sorts of comic designs and colours. No! Well, he lost money over it, for his outraged Rooster flew over the fence and killed his next-door neighbour's Peacock."

He contradicts it being a 28/95 by saying it had a Knight engine!? Would that make it a Mercedes-Knight 16/40-hp or 16/45-hp?

It is a Mercedes 28/95 PS shown at the Berlin auto show in 1921. The ornaments on the aluminium body were chiseled. The bodywork was done by Reutter. Unfortunately I don't know the customer of this car.

It's a 28/95 and the body was made by Reutter. This photo was taken in 1921.
