Where is this early 19th century coat?

[Lady Grey]

The photo comes from
Bridgemanimages.com (put tartan in the search box)

Don Troiani is listed as the copyright photographer
It is listed as being held in a private collection along with a similar kilt.

As I was researching your Arisaid question (in another post) I came across it, I'm wondering if it is part of The Carmichael Collection?
The collection was broken up but there is a possibility that it may be at the West Highland Museum in Fort William.
