What is the value of a Frigidaire stove made by General Motors circa 1950's-60's?

we have this item that we removed from our grandfathers home. can't find a date the info we have is that it was made onlt by general motors. it is a long cabnet with 4 drop down burners. storage cabbnets under it and 4 drawers. on the back side it has a table leave that you can prop up. we would sure like to know of any value.

thank you
