Here are photos of my model of the twin Gemini Telescopes now operating in Hawaii and Chile with financial support from the USA, the UK, Canada, Australia, Brazil, and Argentina. I used a shaving mirror with nearly the correct focal length to represent the 8-m diameter primary mirror, so it does form images at the prime focus in front of the support structure for the secondary mirror, which is not properly figured.

The two images on the right images show the altitude drive. Just like the real telescopes, the drive is a pair of small rubber tires that turn large steel quadrants attached to the tube with the mirror. A precise encoder controls the position on the sky.

The actual telescope structure was manufactured in France and painted a blue very close to the French Meccano medium blue used in the model. The backs of the prewar flexible plates were not such a close match but the yellow cross hatching was useful to repesent the grill work over the air vents on the azimuth plate.
