I only saw one file on the CA-23 at the Melbourne office of the National Archives of Australia. Unfortunately I missed the "Appreciation of Fighter CA 23 [1952]" from the private papers of H.P. Breen. The rest are in Canberra, including the very interesting looking Cabinet paper "Production of two prototypes of a long range all weather attack fighter aircraft CA 23 : Agendum Number - 129/1953 and Attachment : Date of Meeting - 20 August 1953". Which at two folios thick could be a gold mine. Alas this means I'll have to make a visit to our nation's capital.
I've data captured the 'Low speed wind tunnel investigation on the CA-23, a twin seat all weather fighter aircraft', D A Lemaire. This report details effects of various adjustments to the wing planform, flap size, with or without tails, dive brakes, etc. Primary purpose of these tests, carried out in Feb to Aug of 1951, were to explore the low tailplane position. Original position was a high T-tail, then to a position below the fin and both were destabilising.
