As for the VS:
No, there is no place to purchase any sort of photo book of the tartans, though producing such is one project that we have had on the back burner at the STM ever since we acquired a copy. If anyone would like to help sponsor such a project, please let me know!

In the meantime, you can view images of all the tartan illustrations from the book, absolutely for free, on line:

As for the 1819 Key Pattern Book from Wilson's this was not ever a published book, as we think of it. Peter MacDonald's book about the 1819 KPB is very interesting and a must have for tartan enthusiasts, and while it does have some illustrations, most tartans are not illustrated. We have been sold out at the STM for a while now, though we do have a copy in our research library, and I have a personal copy at home. I'll let Peter share more about that excellent book.

While it is not the 1819 KPB, we do have photographs of all the tartans included in a sample book from the 1830-40s era that is most likely Wilsons' cloth.

I have some other photographs of Wilsons tartan from the STA collection which I will one day get around to putting on line, as well.
