When I was a high school student I had a mate who’s Dad worked at WRE / Weapons Research Establishment north of Adelaide. The good old days of A bomb tests and lots of interesting aircraft visiting.
WRE must have been near where RAAF base Edinburgh is today, not as far north as the old RAAF base at Mallala. There I saw my one and only B 29, wasn’t aware then a RAF “Washington”.
I used to get aircraft photo prints from the Adelaide “Advertiser”. May be a line of enquiry via Dr Google, one would assume they haven’t destroyed their historic photographic archives?. They might have something
Timing.. about mid ‘50s..?
