Handlebars are made in 2 separate sections screwed into the Fork Top Yoke.
Saddle is fitted on a sliding tube arrangement in the rear vertical frame tube, pinch bolted in place to suite rider height.
A very secure centre stand is fitted to the frame just below the Gearbox, held up by 2 side springs.
Frame and Forks are in excellent condition the Forks and steering head races having been fully overhauled before painting.
The Frame and Forks have been checked for alignment and are very good despite the small evidence of crash damage that was not possible to remove from the right-hand lower fork.
A Steering Damper of the Andre type is fitted to the top of the Forks anchored to the Fuel Tank top.
Forks have double Damper Discs fitted to the Top Links adjustable by rotating Knurled Brass Hand-wheels.
Steel Mudguards of narrow racing type are fitted over front and rear wheels. Front Wheel is 21" with a 3" Wired edge ribbed tyre. Rear Wheel is 20" with a 350 Avon SM Tyre.
Wheels are Enfield Hubs with Cush-drive rear with 8" Drum Brake operated by Foot Pedal on the left via a Bowdenex double wound cable.
Front 7" Drum Brake operated by inverted Handlebar lever via Bowdenex cable.
Gearbox and Clutch are Sturmey-Archer heavy weight four stud gearbox and Cork Clutch. Drive is 5/8" x 3/8" Primary and Final Drive. Both have original cast Alloy covers.
Fuel/ Oil tank is Nickel plated steel. Approx. capacity 2.5 gall petrol and 3/4 gall Oil. Both have large bore Lever taps. The left fuel tap incorporating a reserve capacity.
Engine Oil is gravity fed to the Best and Lloyd pump on the Mag chain drive cover. The pump delivers an adjustable amount to the Timing chest where it is automatically vacuum fed to the Crankshaft via a hollow timing side Mainshaft.
Engine has only one pair of Cams operating both cylinders' valve gear via levers operated by rollers held between steel plates either side of the cams. Push-rods are adjustable at the top where they operate on flat ended Rocker arms retained by special flat ended pins.
The Rockers run on greased ball races and operate two parallel inlet and two parallel exhaust valves per cylinder in a pent head. No adjustment is provided between each pair of valves. Both pairs of Valves have independent ports only joining at the cast inlet and exhaust manifolds.
Magneto is a Lucas AC2 firing 18mm Spark Plugs that are positioned horizontal in each Cylinder Head.
Two Carburetors are fitted. One to each Cylinder. They are fitted on independent manifolds in a cross-over pattern, the front carb in the conventional rearward facing position and the rear forward facing with a shield to stop ingress of foreign matter.
Four separate Exhaust systems are fitted. The front two 2" pipes fit over the exhaust manifolds and are secured by finned clamps. The two rear pipes fit inside the manifolds and are secured by screwed bolts. All four pipes have separate 'Silent Ghost' silencers fitted at the rear on special secure mountings for racing.
A derivative of the 8/38 British Anzani 8 Valve engine, mounted inverted, was used in the Flying Flea light aircraft made in the late 1920's an example of which is in the Brooklands Museum.
“These Montgomery machines are for the men who prefer a distinctive mount in appearance and performance. That extra degree of soundness – those little touches which distinguish the ‘super’ machine from the mere motor cycle, come naturally to the Montgomery and at a price that is amazingly low.” – Montgomery advertisement.
