I think if you click on [Show Default] in the Template editor in the AdminCP it should show the original template without the modifications, you might be able to copy it from there. If not then you could just create an unmodified style and copy it from there.

Alternatively you could click on the [View History] link in the template editor and compare the different versions. Slightly more complicated but easier if you know what your doing.
