Hi, please check out the picture. I have been given an old pizza oven and for the life of me I can't figure out how these parts all go together.

I think it's a pizza oven. It could actually be something else. I think I might be missing a load of pieces.

I was thinking it should have a flat bottom and then a dome on top. I can see from other images that the half dome on the right is probably the doorway and I think there is supposed to be a chimney that goes on top.

But I can't figure out the other pieces.

Shouldn't the floor of the pizza oven be flat, but all the other pieces have lips on them. Maybe they are supposed to be filled with concrete or maybe the semi-circle pieces are from something else.

If I am missing the chimney I am probably missing other pieces too.

I know it should have heat bricks and insulation, but I can't even mock it up, I am so confused. At this point it probably would have been easier to build a concrete pizza oven from scratch.

If you have one of these, then drop me some hints, would be appreciated.
Dylan.
