This business, initially at 213–7 Elizabeth Street, Sydney, is widely known as the manufacturer of Waratah motorcycles from 1914 to 1948.

[4] Subsequent addresses of 255-259 Elizabeth St by the early 1920s, and 117 Goulburn St in the later 1920s are detailed in newspaper advertising, also detailing that the business changed its name to P.and R. Williams Pty Ltd, and later moved to 74-78 Wentworth Avenue Surry Hills.

Initially, they made small machines assembled from predominantly British components, including Villiers engines, Sun frames, Druid and Brampton forks.

In the later years (post World War II), they badge engineered using, it is believed, Norman and Excelsior machines.

There is no detailed definitive history of the Waratah models, but from books,[4] press articles, sales brochures and adverts, the following outline picture seems clear: More details are known for certain years: An advertisement in 1916 selling a second-hand Waratah refers to it as "3.5 h.p.

were manufactured by The Valveless Two Stroke Engine Company Ltd. of Birmingham, England, and sold exclusively to Sun Cycle & Fittings Co. Ltd. (whose frames were used on Waratah motorcycles).

An advert in the Townsville Daily Bulletin describes a Waratah machine with a Villiers Two-Stroke engine and two speed gearbox that gives 110 mpg and that "easily climbs Stanton Hill on top gear".

[26] The advert shows a picture of a machine with enclosed primary chain and a belt drive to the rear wheel, an angular fuel tank slung under the top frame tube, no obvious electrics and no suspension other than seat springs.

[43] Other (also apparently promotional) press coverage[53] provided more detail, but without being explicit about which model, perhaps it applies to both: "The 1929 model Waratah is a machine which is obviously suited to the utility rider, as it possesses not only the characteristic qualities of two-stroke construction, but is exceptionally well equipped in all ways.

General completeness, such as a cushion drive shock absorber, as well as automatic lubrication, twist grip control, balloon tyres, front and rear thumb adjusting brakes, &c., all indicate that the manufacturers realise that the utility rider wants something more than economy and light weight.

The performance of the engine, too, is much better than would be expected with a machine of this class, as it is capable of high maximum speed, although these qualities of speed do not in any way affect the smooth running and slow top-gear performance of the machine."

Whilst it does not state the year and can hardly be considered a reliable source, it is mentioned here for completeness.)

[84] They were both offered in "R" and "D" versions: There was also a Model "125" Two Speed, which was an ultra light utility machine, with an Excelsior Goblin MK.
