Gerald_G that's a very interesting reflector oven.

They can certainly be made in a variety of ways.
I can see pictures would be a big help.
Mine unfortunately are after pictures, I didn't think of it while I was cooking my mexican cornbread. But the general idea will still be there. The cornbread came out nicely cooked and was enjoyed at the Dam Gathering.
Inside box covered in foil
Foil on ground, with 2 bricks covered in foil with rack & I used foil pie plate to put charcoals in. (when really cooking the coals were hot & white)
I cooked the cornbread in a disposible foil pan, any regular pan that could be used in oven can be used.
Then the box goes over the top, and need small rock or something to let some air in.
Each brigette equals about 40 degrees heat. So nine would be about 360 degrees. It also depends on how long it takes to cook what you are cooking, as more may need to be added as you go along.
So for someone who wants to try something different or who doesn't own a dutch oven yet, it can be fun to try & is cheap. Anything you can cook in an oven can be cooked in it. Pizza, cake, cupcakes, cookies, cornbread are a few of the things I have done in the past.
