The Debenham Sisters
Russell was a motorcycle designed and built by Edgar Russell of Derby, in 1911.
The machine was quite advanced for the times and had a 3½ hp single with ohv, each in a cage that screwed to the head. It also had a B and B carburettor, Bosch magneto and stiffening ribs cast into the crankcase. It had a single speed and belt drive.
Its creator used it for a year or so, but it did not go into production.
There was another Russell built by a different firm in 1913
