Hey LK,
My sister in law and my bro, when he was alive, were antique dealers. Unless that Frigidaire is in working good condition and rust free, It isn't really for high resale value. If you plan on fixing it and keeping it, ok cool it has value to you, but selling in the condition it is in won't get you a high value. Plus, Antique dealers look for original parts, so if you are going to restore it you should look for original parts. Also color is a factor as well. My sister-in-law told me once that collectors are looking more for appliances in that ugly aweful tacky avocado color and the sky blue or cream. Sky Blue more because of the fact that general motors used the color for cars and went with it for appliances in the 50's.
So depending on your purpose it is a score or fail
