My Grandmother gave me a GE can opener, It's probably one of the first made by GE as I can't find a model number on it. It's tan front, brown back, stands upright, and has a CAT. NO. D2-EC32. I've been in possession of it for about three years now and the smallest gear in the gear train broke in half right off the pinion. I'm wondering if there is any way for me to replace it as it's the best can opener I've ever owned.
