A Brief History of the Marque
The Macklum was in production for only two
years. Mr. F. MacCallum designed it, and it was manufactured by Alfred
Wiseman & Co, the company that made Sirrah and Verus Motorcycles.
Wiseman built motorcycles in the early 1920s (Tragatsch says 1922-1925)
using a variety of proprietary engines from the likes of Blackburne,
Bradshaw, JAP and Union as well as some of its own manufacture.
A single frame design capable of
accommodating various different power units was a Sirrah hallmark, and
its manufacturer claimed that the Sirrah would "stand up against bad
weather, bad roads, bad treatment, and win through every time."
