Hi Cuda:
It was the paint job that got me on the trail. I have a couple of good Indian sites bookmarked and that is where I found your car.
What the sites indicate is that the Indians have a great appreciation for colors and in the day, those who had the money had their cars painted in some marvelous color combinations. Bear in mind that the "Titled" Indian Royalty of the Raj era in the last throes of the Empire had a lot, a lot of disposable income. Part of the whole system was that they displayed their wealth in a very public way that would not really be acceptable today.
As to the Maybach, it is definitely a coach built vehicle but not garish which seems to be typical of the Maharajahs cars of the day. The paint schemes were what set them off. Note that the grille has been tarted up a bit and it has the typical Spohn fender skirts. I am trying to find a photo of the interior as this where these guys also tended to get a bit creative in their wishes.
Here is another shot from the other side.
