I know I've read it here before, but can't find it now to confirm. I have a Fisher stove that I believe to be a Grandma. I can't get a picture of it as it's buried in the garage, but I could get a tape measure across the top. The top plate is 29.25" wide. WeldrDave Coaly
I have several owners manuals and the 1979 one I'm looking at say's: Grandpa; W 30" Depth 30-11/16" H 33-1/2" Grandma; W 25-1/2" Depth 30-11/16" H 33-1/2" Now, there wiil be and is many slight variations from different manufactures for saving $$$ and such but "all" will be withing that standard specification.
