More on the Hardwick Stove

Last week I wrote about my mysterious stove/oven manufactured by the Hardwick Stove Company. Thank you to Elyse for comments. However, I realized that more pictures would be helpful for accurate guesses. Rather than ramble on without images, here are some photos of the unit and a description to the best of my ability. Click on any image to enlarge (and then you should be able to zoom in from there.)

Just a refresher: the hood is not part of the stove/oven unit.

The gas burners when the metal plate is lifted. There are four burners.

The oven is on the right, and a compartment box is on the left. There is a lever that says open/shut. Don't mind Izzy - she just likes to get in the way. Beneath the left door is a storage compartment. Beneath the oven is a broiler.

Another shot, but Izzy is in the way...

A close up of the box when opened. I believe it has wood ashes, but since I know nothing of this stove, I'm not making any bets.

When you lift up one of the warming plates, this is what appears below.

Any thoughts? I’ve just found myantiquestove.com, so perhaps I’ll find some leads there. Thank you readers for being my sounding board on this matter. I appreciate it. I hope you enjoy the puzzle.
