Of the machines handled by this firm many are well-known models, for
which they are selling agents. These include the Ariel, Enfield, Rex,
Motosacoche, A.J.S., Matchless, Hobart Bird. F.N., etc. In addition,
they have now introduced a motor-cycle, and also a side car of their
own, under the name "Portland." The motor-cycle of 3.75 H.P., has a.
Peugeot or J.A.P. engine to choice, B. and B. carburetter Bosch magneto,
Druid spring forks, and tyres to choice. The price is £40 with the
Peugeot and £38 with the J.A.P. engine. The side car is fitted with .. in. tyre, Continental or Hutchinson, to choice, and sells at 5 guineas
to 7 guineas, the latter being a de luxe model with cane basket work.
1913 Still with belt drive, the machines now had 4hp JAP or 3.5hp and 4.25hp Precision engines.
1920 They continued to sell their own brand of machine, built by a trade supplier, using components such as 269cc Arden two-stroke engine, Amac carburettor, two-speed Albion gearbox and Saxon forks. These lightweight machines were typical of the period, but a down-turn in trade saw them slip from the market.
