Tetenal Art Museum could be any one of a number of papers. I know it was Agfa for a while, and some has been Ilford.
If you have any chance of getting hole of Fortezo Museum, that is a wonderful paper both for lith and "ordinary" work.
Ilford's papers are wonderfully stable and predictable, meaning that they give the same results in a wide range of different developers. Just what you want for a consistent body of work, but exactly what you don't want for lith printing.
