Your house probably used to have those old bilco doors with an entry to the basement from the outside. My moms house used to have them too, but at some point, some genius decided to cover it all up. Probably leaky or something.We have the same stove in our basement. I wish I knew how the heck they got it down there! Our kids are 5th generation in this house. Unless they moved the stove here from somewhere else, our house was built in the early 30's. Maybe that will help you with the age?
H&R, I have those same 2 colors, plus a very light, 2 toned pink.
