I can tell you this, it is quite rare. I have searched and found similar steam Engine Plants but none exactly the same and absolutely none with the flower detail in the vents.
If you look at the photos the flower petals are metal on all the others I found the flower petals are stamped out of the metal. This is large and in great condition. Burner is in great shape. Dimensions of the wood and painted tin base are.
