Part 1: The green stereoplotter is founded on a U-shaped mainframe with three feet, one at each point. The mainframe can separate from the top elements which form a series of detachable parts.
On either side of the front of the mainframe's base are two silver turning wheels with black handles. The left-hand side also has a smaller turning wheel, placed above the main handle. On the left-hand side of the stereoplotter is a foot pedal attached to the mainframe by a silver cord. Attached to the foot pedal is a maker's plate with the text, "GHIELMETTI & Cie. AG. / SOLOTHURIN SCHWEIZ / A 10 / V 500 / 50 / No. 188117 PO". On the right-hand side is a cylindrical weight held by a chain. On the side of the right-hand foot is two metal ports with “Y / X” engraved next to them in white. On the back of this left-hand leg is a sticker with hand-written text, "L H /.".
On the rear leg is a sticker with the hand-written text, "3 / REAR". Sitting on top of the rear leg is a silver electrical box with a gold sticker which reads, "Electra". Attached to this box are two black cords which run to the lamps above. There are also two white cords, one has a black power plug on one end, the other has a white power plug which is connected to a brown power cord, which runs into the rear of the stereoplotter mainframe.
Sitting across the width of the mainframe is a slide rule which can be slid backwards and forwards using the silver and black handles attached to each leg. Various measurements are placed across this device. A protruding green and black handle allows the device to be adjusted. Attached to rear of this device is a white coiled cord which attaches to the rear of the mainframe. At the front of this part is a viewing plate with a reticle. Attached to the right-hand side of this part is a long black pole which attaches to a black plate which rests on the ground. On the top of the device are two metal poles which are placed vertically in a V-shaped position. These extend into the top half of the stereoplotter.
At the front of the stereoplotter, attached to the mainframe is a large arch which a black maker’s plate which reads, “WILD / HEERBRUGG / Made in Switzerland / A8-7 5”. At the top of this arch is another platform consisting of multiple parts. On each side of the top of the stereoplotter is rounded frame on which a domed lamp overhangs a black plate with a rectangular cut-out. The plate is enclosed with various pieces of metal teeth lined with measurements. At the rear of these circled frames are a series of yellow power cords which attach to various other parts of the stereoplotter. Within each frame is an adjustable lens, and a black chained pulley system. On either side of the frame is two vertical silver measuring rules, and a circular measuring device. At the front of each rounded frame is a small, circular glass lens with “WILD / HEERBURGG / 4X” engraved in white, and an adjustable silver dial.
Beneath each circular frame is a small bellow which connects to a large black tube which runs across the front of the stereoplotter. Beneath the black tube on the left-hand side is a small measuring rule. At the centre of the black tube is an eyepiece, and to the right, a large plastic clipboard, for paper to rest. Behind the eyepiece is a series of three silver bars which can be adjusted with a small crank handle on the right. Various measurements decorate the front tube, the crank handle and two vertical rules. Each vertical rule has a small black lens with “WILD / HEERBURGG / 4X” engraved in white. Two adjustable silver dials sit behind the silver bars.
