I need help/advice for my Universal Wood Cook Stove from early 1920's

[Topia Farm]

Hello all! I am new here and purchased this beautiful stove from a family who has owned it since the 60's I believe. From the research I have done, which I have quickly learned there is not much info on these particular stoves, it is from 1918-early 1920's. It is overall in great condition for the age with only minimal rust in the upper shelf where it touches the stove pipe area. I definitely need to do a thorough maintenance to this stove, seal all the cracks and oil it etc. My questions are:
-Does anyone happen to have any good history on these? I love researching and learning about the vintage items I have but seriously I have found very few resources with minimal info.
-It does not have the oven rack shelf, where does everyone buy their replacements? Its approximately 17" x 17"
-I also need the ash bin, I heard these could be ordered through Lehmans but I didn't see any online (approximately 6" x 17")
-The plates/burneres are cracked but I am guessing this is not a huge issue? They seem to be in functional shape
-What are these teardrop pieces in the back? What is their function and what are they called? I am missing one and don't even know how to search for a replacement.

Thanks so much for all your help in advance.

Just a guess. the teardrop lids might be to cover holes for water-jacket piping.

"The firm of Cribben & Sexton was originally founded in 1873 and are perhaps best known for the stoves, heaters and other items at its Chicago factory throughout much of the early 20th century."

Another interesting artifact that will be featured pretty prominently in the Lopez Adobe once it reopens is the Cribben & Sexton Universal stove that is currently on display in the 1920s-styled…

If they are like mine the “tear drop” thing are to set things on to keep them warm. Like coffee pots.
