Pathescope 200B - 9,5 mm - 1933. In France was sold as Pathe B
Gerald McKee in his book - “The Home Cinema Classic Home Movie Projectors 1922-1940” in 1989, says:
“Of all 9,5 mm projectors the 200B must surely be the most famous. Many have still survived to today, being successfully used by many collectors to project their films. Perhaps an element of its quality and prestige was that it appeared in 1933, when Pathescope was at its peak, confident as a leader in the supply of equipment and library films foe the home movie enthusiasts.”
The projector was made by Pathescope; at Manchester works of the Salford Electrical Instrument Co., in England.
Originally, there were three different versions of the 200B. The difference was the type of lamp built-in:
- a mains model with 240 volt motor with a 250 watt lamp;
- a resistance model with a 110 volt motor and 200 watt lamp;
- a transformer model with 50 volt motor and 250 watt lamp;
In a Pathe catalogue you could order another type of the projector; with rewind motor 12 volt and 50 volt for use from a car batteries.
The resistance model is the most common.
Features of the projector:
- Lens made in England f 2,3 F=32 mm; focal length, giving a picture four feet wide at a throw of 16 feet;
- The lamp 200 watt is a tubular type with Pathe T-piece is secured, providing in a pre-focuse type of cap;
 
The lamp must be tighten by screw outside the lamphouse. The lamp house is asbestos lined;
- the gate is as the fixed channel with the guide way;
- Film path - conventional for two sprocket mechanisms;
- The motor drive is connected by rubber belt. The speed of the motor and projection speed can be regulating by means of the knob on the right hand side of the lamp house ( Pict.);
- The shutter fitted has two blades;
- The projector is fitted with Tilting Lock Nut and the projector can be tilt at the desired angle;
- The projector is fitted with the arms which can take 300 ft reels.
The projector needs lubrication. It must be remove mechanism covers on either side of the projector and apply a few drops of oil to all the points marked in red on the projector; 8 points at the back, 7 at the front, and one on top - total 16 points.
The optical system: lamp, condenser, reflector must be clean. The film guide way must be clean from film emulsion.
Sometimes the cable connected to the resistance box should be checked. It occurred that often the rubber covering of the wires is rotten and wires can short out. Where the cable goes to the RB it can twist around and all the rubber insulation can brake of the wire and can cause an electrical short (Pict.).
Production number 107118 BC - the serial number is stamped at the back of the lower spool arm pivot

Specto Standard - Type B - 9,5 mm - 1948 - 1959
The projector was made by Specto Ltd England Windsor. It is a British design by a refugee Czech engineer J,Danek. The first models 9,5 mm were produced, in 1935, at Danek’s small factory at Farnham Royal in Buckinghamshire. The powered motor was wound for 240 volts. The speed control was by rheostat. The lamp was 30 volt 100 watt. The lamp was fed by a step-down transformer, when used for 200 to 240 volt A.C. mains operation or by separate resistance for D.C. mains. The gearbox was running in an oil bath, driven by the motor via a rubber belt.
By 1938 the SPECTO moved to new Windsor factory, and completely manufactured at the Windsor works.
In 1948 appeared a new SPECTO. The main change was to have a chain driven from the gearbox to the sprockets.

The body
The main body of the projector is die-cast aluminium and finish in silver gray wrinkle enamel. In the factory leaflet we are reading: “We make all parts ourselves on precision machinery and even do our own die-casting All wearing parts are made of high tensile steel, machined to .00025 accuracy”. The spool arms are folded to form carrying handle. The projector weight is 16 3/4 lb.
The power
The projector is driven by motor. In a sealed gearbox are gears, spiral and worm drives, ball bearings and rewind clutch. They run in an oil bath. After ca 20 hours running - XL type motor oil should be added to gear box. Transmission from motor to mechanism is by shock absorbing belt and the sprockets are driven by a chain.
The lamp
The standard model is with 30 v. 100 watt lamp. The lamp is matched to a specially designed condenser and an adjustable reflector (Pict 1) . The lamp is controlled by a separate switch and will not light until the motor and fan are started (Pict 1 & 2).
The lens
The lens is a wide aperture projection lens. Our projector is supplied with: Taylor-Hobson 1½ inch projection lens f/1.9; Made in England. The lens is coated.
The film loading
The spool arms in our projector are suitable for 900 feet of film. The film has to be insert between the top sprocket and roller sprocket guides, next into gate and between the bottom sprocket. The film can be rewind engaging the rewind mechanism by turning the lever to rewind position. The lever can be removed and to check of the oil level in the gearbox.
The projector has dual claw mechanism (Pict 2) and two cams.
The gate is hinged and it is easy to clean.
The projector is in a gray fibre case with compartments for spare lamp, lead, spools, etc.
