Oven temperatures...

#1
We just bought a place which has a White Westinghouse Oven. As I was trying to figure out how to use it, I noticed that the temperature dial for the oven had NO NUMBERS on it. Any idea how you are supposed to cook something at 350 degrees? Any idea how hot these oven go to and what the largest dot on my dial would actually represent in terms of temperature?
Even though this is a "decent" size oven, I feel like I am playing with an Easy Bake Oven from childhood.
