First of sixty-four Australian Demons for the R.A A.F.
A1 was first allotted to Imperial Gift D.H.9As in 1920. It was re-allotted in 1934 when eighteen Hawker Demons were purchased from Britain, the first of which is shown above before delivery. By 1939 over sixty Demons were numbered in the A1 series.

The A52 series was divided into blocks. Ex-R.A.F. Mosquito F2 (DD664) shipped to Australia was numbered A52-1001. Australian-built FB40s were numbered from A52-1; PR41s from A52-300 and the FB41s (shown illustrated) from AS2-500.
