Hi, I've seen a few of these posts around, and need some help of my own. Belonged to my now deceased grandparents, and I'm trying to fix and keep what I can. Was a portable, but was then built in, making it difficult to find and reach the model number, hoping once I identify it I may be able to fix it. Looks similar to the K series, but the controls are decidedly different (and missing the on/off switch), but have waded through all the images and manuals I can find, but have found no trace of it. Not in the greatest of shape, but can certainly touch up the exterior. Thanks!
