The book is The Complete Book of Tartan. Its accuracy is a bit spotty in places, but it has some nice pictures. I'll have to scan and upload some of them when I get the time.

The painting of Rob Roy is part of the Bridgeman Art Library. The original is owned by the Sheffield Galleries & Museums Trust, and is apparently housed in the Graves Gallery:
