Ixixly, if you google up "ADF Serials - DeHaviland Caribou" and scroll through the various photographs you will find examples of Augmentor tubes on the 'Bou.
The Convair 440 Metropolitan operated by the RAAF No. 34 Squadron based at Canberra in the Sixties were equipped with augmentor tubes to the P&W R2800 engines. In fact they were a major selling point on Convairs when they were first produced I believe. They were advertised to augment more exhaust thrust and thus extra IAS.
