"Scindia House"

[gracol]

I think ShaunJ that is Scandia which apparently is an ancient and poetic name for Scandinavia.
You are right bearkat it seems logical that the sign is probably local.
I am wondering now if most,if not all,of these Scindias relate to the Scindias of Gwalior State India.They have ruled the State,and still do.A lot on the web (eg "Jai Vilas Palace).

Update.
The founder and director of the Scindia Steam Navigation Co Ltd contacted me and was very interested in the sign.
He recently visited London on business, we met and he now has the sign, and is eager to do further research on his return.
