Bach Itaian Concerto - Second Movement

Does anyone have a commentary or urtext for the Italian concerto?

I have the Bulow edition, but it has some differences with the Leipzig BGA edition and also an edition I found online somewhere which is edited by Mortimer Wilson. For example, where the RH comes in, Bulow has it coming in unornamented on the second quaver of the bar, whereas the BGA has it on the first quaver with an inverted mordent (which is what :rectum: plays). There are also some accidentals varying between the editions.

Many thanks…

Play it as you like. I made a long slow trill on the first note of the right hand, which sounded very good. I believe that there was a mordent in my Henle Urtext.
