Where is this early 19th century coat?

Thank you but no, I'm looking for the original coat.

Luke, thank you for the steer. I went straight to the source and found it here where it is described as - Man's coat and waistcoat of Highland tartan circa 1780-90.

I'd have put it slightly later, more like 1800-10. What is certain is that even from a poor quality image it's possible to tell that it's Wilsons' cloth and not 'Highland tartan'.

I've emailed to ask if they know where this coat is.
