Telechron's last cyclometer clock was the only one made of metal.  It's really very nice tho' a little on the small side.  Unlike earlier models, the numbers were protected with a plastic cover and you set the time by rotating the wheels from the bottom.  The original color was called "gunmetal" but they always end up this brown/bronze hue.  If you see one gleaming like a new penny, it wasn't a rare variation--it's just been polished.
