P&R
Manufactured by P & R Williams, 74-78 Wentworth Street, Sydney, NSW.
Built from 1920 to 1926, these were lightweight two-strokes which initially used a 2¾ h.p. engine of their own design with single-speed or a two-speed gearbox. Later models were fitted with Villiers engines and were identical to the Waratah which was built by Williams Bros, another family company. The two firms combined in the 1930s.

Examiner (Launceston Tas.) Mon 29 Mar 1915
The same article mentions the "Precision Junior" motorcycle, so it seems likely that this firm was responsible for the "Perfect Precision".

PGM
In 2015 Paul G. Maloney, a man of considerable experience in the fields Moto GP , F1 and WSBK as an engineer, gathered a team in Melbourne to meld a pair of Yamaha YZF-R1 engines into an extremely compact V8 of almost 2000cc. The result was an attractive beast capable of melting the paint off almost anything, with the possible exception of an RAAF Hornet.
Specification include 334 hp @ 12,800 rpm from the 40 valve engine, carbon fibre frame, Öhlins suspension front and rear, with state of the art brakes, wheels and tyres.
Price: US$180,000
