Value of depression era refrigerator

I would have sent a pic but I think this link shows almost exactly what the item I have looks like. http://www.antiqueappliances.com/monitor_top_refrigerators.htm. At the very top there are 5 or 6  refrigerators pictured at an angle in a line. The last 2 on the right look like what I have, except for mine does not have the monitor top thing on top. My dad kept in his garage for storing things. It was never hooked up to any electricity. Its got some rust, but mostly a lot of scratches and dirt. On the very bottom it reads: General Electric, Type M-6-A 5, U.S. Patent 1684716 18110615, Schenectady, N.Y., 5366540 (The last line of numbers reads much larger than the rest of enscription.) I'm not interested in selling, just want to know if it might have some value, and or if it is worth restoring.
