Corning does not make wall ovens. They made the tempered glass that covered most of them and the ranges back in the 60's and 70's and the word "Corning" was prominently displayed on the front. They also made the first ceramic cooktops that later became what is known today as Ceran.
Most likely that is a Modern Maid oven with the model you described. And no, the hinges and door springs won't be available for an old model like that. I saw the article you were describing on the "other forum".
