Help Identifying Cast Iron

[JPowell]

I have two cast Iron kettles or bowls (not sure exactly what they are). There is no company name, but they are both marked made in Belgium. At the top one say 3/4 and the other is marked 1/2. Can anyone tell me any information about these. I have attached pictures.

Any pictures of the markings, bail ears and bottoms. Also how about some dimensions for them.

I have a large round bottom kettle I am also trying to identify it would be interesting if they have any similarities.
