Alfred Wiseman of Birmingham built a number of motorcycles in the 1920s, including Sirrah and Verus.
Sirrah motorcycles were produced from 1921 to 1925.
The range expanded quickly and included models with a wide range of capacities: from Blackburne; JAP; Bradshaw; Barr and Stroud; and Wiseman. All had Burman gearboxes and the frames and forks were conventional.
1923 Late in the year they adopted a new universal frame for all models with the tubing formed to avoid all but one joint, which was welded rather than brazed and lugged.
1925 Motorcycle production came to a close.
Note: When production ended, the name of Sirrah had already found its way onto a number of
special purpose machines, including an inspection trolley that could run on South American railway
lines. A similar device that could run on road or rail was also produced for the Indian railways.
Wiseman continued their involvment with railways until 1962 when the firm was acquired by Ruston & Hornsby.
All Classes catered for. T.T., Touring, and Sidecar Machines
THERE are few firms who make a wider range of models than Alfred Wiseman, Ltd., Glover Street, Birmingham. In addition to the deservedly familiar Verus, this concern is responsible for the lesser-known, but nevertheless popular, Sirrah lightweight. It may come as a surprise to many that during this year 250 Sirrah machines of one model alone were sold.
For 1922 the Sirrah range is being extended to include almost every type between the single-speed lightweight and a 5-6 h.p. J.A.P.-engined twin with all-chain drive and 26x3in. Dunlop Magnum tyres. Intended as a double-purpose mount, the latter machine is most attractive, both in specification and appearance, and its very short wheelbase should ensure its popularity as a solo mount as well as with a sidecar.
Massive, but clean mudguards (8in. in front), a saddle tank, Brampton forks, a Webb front brake, Sturmey three-speed gear box, and final chain drive through an Enfield cush hub are the salient features of the specification; but it must also be mentioned that the frame is particularly neat and strong, and has survived nearly a year's severe road testing.
At the other end of the scale, the Sirrah two-stroke has a Union (70x76 mm. =293 c.c.) engine, and when fitted with a gear box (Burman), either a plain two-speed or a two-speed with clutch and kick-starter may be supplied. Footboards or footrests are optional. This model, like all its namesakes, will sell at a very competitive price, but not at the expense of finish and general quality.
Coming to the larger lightweights, there is a choice of belt or chain drive, of 2¾ h.p. Blackburne, or 2¼ h.p. and... (continued p513)
