I am also working on the Western-Holly Robertshaw oven. Because of the self-venting many of the clock/timer knobs have been burned by the heat and crumbled away. I could also use some racks for the broiler. I love the way this oven cooks. Although it is small, it cooks to perfection.
Look at this Roper oven. Please scroll down for the details! Check out the burner grates!
