Staffel of Jagdgeschwader 52 (JG 52—52nd Fighter Wing), succeeding Oberleutnant Karl-Heinz Plücker who was killed in action.

[4] On 16 July, Wolfrum again became a double "ace-in-a-day" when he claimed ten aircraft shot down in combat near Kamionka, northeast of Lviv.

[1] On 31 August 1944, Oberst (Colonel) Dietrich Hrabak, Geschwaderkommodore (wing commander) of JG 52 submitted a report, requesting a preferential promotion for Wolfrum to Oberleutnant (first lieutenant).

[9] Following the end of World War II, according to Wolfrum's own account, he and Hans-Ulrich Rudel were in contact in the first years.

Wolfrum's girlfriend Irene Rühl had a friend who worked for the Americans as a secretary at a hospital in Fürth where Rudel was being treated.

With the aid of these comrades, Rudel had set up a smuggling ring across the various zones of Allied-occupied Germany.

Rudel and his men built an illegal business, disguised as a haulage company, around this discrepancy in exchange rates by smuggling large sums of money from one zone to another, buying and selling currency with a profitable margin.

[12] Wolfrum then became a successful aerobatics pilot, winning the German Championship in 1962 and taking second place in 1961, 1963, 1964 and 1966.
