How old is king stove and range co model 40a?

Surprisingly not very old.....

I believe the King Stove And Range Co. Model 200 "Fatso" is anywhere between 20 to almost 40 years old. I own one, and looked up the info on the internet several years ago (that info seems to have disappeared from the Internet). If I remember correctly production began sometime in the early 70's and ended in the late 80's to early 90's.

It was designed by King stove and Range as a reproduction of a laundry stove. Laundry stoves were used back in the day before hot water heaters, and boilers. They would use this style stove with its broad flat top to heat up big kettles of water for laundry, and probably bathing.
