big old oven stuck in a basement

So i have a lady who i already did a pick up from and is a good client of mine who has two big old stoves in her basment that are in her basement and i cant seem to find away to get them out. They wont fit in the cubby that the door from the outside down to the basement because its too small amd i cant go through the house cause because there isnt enough room between the front door and the porch wall and the back door is too narrow. Now it had to have gotten down there some how i suspect the front porch wall was built after the fact
And because its old i have a hard tom justifying just taking it apart and bringing it upnin peices cause its ild and i can prob get goo $$$ for it
Soo any ideas guys would be greatly apprciated

Look up the make, model and if possible the year, just like a car and see if there is a demand for it or its piece. If there is a demand, then disassemble it and take pics of the disassembly. If there isn't a demand for it then take it apart however you want to.
