Monarch wood/coal stove

This stove is at least 200 to 300 years old. This belonged to my husband's great grandmother. As you will see from the pics it has held up well it was used about 30 years ago but has been in storage since that time. We are looking to sell it. I have not been able to find out what the number 3 stands for that is stamped on the side. All of the parts are original. No handles missing. I also have some other cast iron products that could go with the stove. Let me know what you think.

Good
