The features on the six-20 brownie junior are incorrect. It opens from the back, the handle is diagonal, the top viewfinder is on the wrong side and it is too small.
2a Cartridge Hawkeye and Rainbow Hawkeye are basically the same, the Rainbow's came in a variety of colors. I believe they are closest to your example. They all had small differences over time, plus European Kodak's sometimes differed from US models.
Perhaps the photograph could be scanned with higher quality, it might show more detail of the front of the camera, I recently scanned some 6cmx9cm photos and could actually read the title of a book someone was holding 10 feet from the camera.
