Lux Counter Top Timer
This is an older timer by Lux. It has an all metal housing and a plastic knob. Although this has the same style mechanics as the "long ring" units, it only sounds a single chime at the end of the cycle. I'm not sure of the model or year on this one.
This is another one in red. This has a slightly different face plate with "Minute Minder" and numbers in red. As you can see the faceplate is dirty. I cleaned it lightly, as I didn't want to risk losing the numbers.
