Wood burning cast iron pot

Hello.Could anyone tell me what my cast iron pot is called and when it was made and where identifying marks can be found?It is a round pot.It is tapered down. It has tabs in it (to hold a grill ?) and a sliding door on the side (to add wood?)a hole at the bottom with a catch plate underneath the pot. I wonder where I could find a picture of a similar one.Thanks

Just found that the pot has "Japan" Stamped on it,so it probably is not collectible.

Sounds like a small hibachi. There are some portable grills from BSR and subsequently Lodge called Sportsman Grills that are popular in the cast iron collectibles community.
