Hello, can anyone point me in the right direction on finding out the value of an older Hearthstone II soapstone stove. I think that is the correct model, the plate has a serial number but lists both the I & II models. My wife and I received it from a coworker years ago and never used it. We are getting our house ready to sell and we would like to get rid of it. I'm not sure if I should sell it just for parts or if someone can use it at all. I'm sure it would have to be gone through and checked, it has sat for many years out on our porch. Any input or help would be appreciated.
