I guessed that if I couldn't find it on the web then it probably did not exist.

But I think I can send you some good news, I remembered seeing a reference to Titsworth's co in Piston and Hatchers book on Wilson's Creek and on checking it again they refer to a muster roll for this company in the Dandridge McRae papers. On checking this out, I find not only the Titsworth muster roll (Item 54) but a great number of of other muster rolls which I think may be of interest to you.

Now if only I can locate the muster roll for Reid's Fort Smith Artillery........
