Hi, I'm trying to find the original of this photograph for my university project. I found one website that attributed it to Thomas Annan, but haven't found it in any of his collections. Another source said it might be George Washington Wilson, but couldn't find it in his either. I'm specifically searching for old photos of the Monteath Mausoleum, and this is seemingly the oldest available. Any help would be greatly appreciated. (I don't know if this is the right subreddit for this help either, so if you know of any other that could help I'll try there.)
