Sorry to join this conversation late, but as covered above II./JG52 swallowed up pretty much all of the available aircraft from the dissolution of I./JG53 and II./JG51 ("Rosemarie", Bf 109G-10, White 11+- at Neubiberg even shows the overpaint of the previous II./JG51 II. gruppe bar forward of the overpainted number - the usual II./JG51 position).

The yellow cowl/rudder was introduced by 4. Fliegerkorps around 7th March 1945 and I have it, evidenced by photos in my collection, on at least the following types:

Hs 126,
Hs 129,
Bf 109G, K
Fw 190F, D
Fw 189,
He 111,
Ju 188,
Ju 87,
Si 204

Again sorry to be late for the party, as it were,

Cheers,
Chris
