Attached is a guitar part for the Beethoven Duo for Clarinet and Bassoon WoO27 No. 2 in F Major. Other parts are at:

In addition there is a version, (both parts), in E Major which may be more suitable if the guitarist wants to thicken the bass line up with chords. Then the top line might suit a violin or flute best.
Another way of using the E Major version is with a treble recorder at A=415 on the top line!
I am sorry I have not examined the guitar parts in the microscopic detail which I usually do for the primary version, checking the position of all expression marks etc. and any objects too close together, (computer typesetting is not always perfect), but the parts look superficially very clear.
