After the first performance in 1808 a first edition and parts were made. But these did not contain some things in the original orchestral parts.
This set of parts was hardly known about and was found in the Lobkowicz archive in Nelehozeves, Czechia. This resulted in some errors in the first edition and subsequent editions being researched and rectified.
I have typeset the part as closely as I am able to the original. You can download it here.
Here is a video about this original timpani part.
