Those little stoves were once almost a necessity in most homes, since they were sold as and known as a "laundry stove". Every Monday they got put to use heating the water, with a "copper wash boiler" sitting on top. Some of the models (such as yours) had a water jacket that was hooked up to a galvanized storage tank sitting next to them on a cast iron stand. Even after the laundry went through all the boiling, scrubbing, washing and drying, the stove was still needed...for ironing with sad irons heated on the top. They were a common hardware store and mail order catalog item probably up through WWII.
Todays value would be in the $50 to $150 range I'm guessing.
