Original 1940's-50's Vintage O'Keefe & Merritt Stove Top Folding Vanishing Shelf Chrome Support Rod. This is a very nice bright and shiny support rod. As close to new chrome as one can get in a used chrome part. These rods mount on the L&R sides of the side stove panels, they lift up and support the vanishing self. Fit either left or right side. 

Please note OK&M used two styles, they both look the same. One style was thicker and the other was thinner. This is the more common thicker style. It just gently 'pops in' on either side panel.
