UH-1B A2-1020's tailboom is preserved in the heritage museum at RAAF Townsville. The remainder of this Huey, that was involved in one of the most well known RAAF operations in Vietnam (see http://www.adf-serials.com/3a2.htm) is preserved in the RAF museum at Point Cook (be it with a different airframe's tailboom...).

This historic Huey saw action with 9 Squadron RAAF at the battle of Long Tan during the war in Vietnam. Allocated the USAF serial 63-13588, but delivered new to the RAAF on 12 Dec 1964 (incidentally, just a couple of weeks before I was born). Based at Vung Tau from mid-1966. Returned to Australia in April 1968 and used in the SAR role with 5 Squadron until retired in June 1984. Allocated to the School of Radio at RAAF Laverton until 1993, then transferred to the RAAF Museum and restored 2000-02.
