I know almost nothing about Adox, other than it was a German company which produced a few cameras, including this folder; to my eye it looks like a copy of an Agfa Billy. They also made a few other folders which also look like Agfa copies, but I'm not expert enough to know. From what little I can glean on the internet, Adox made cameras between the wars, went bankrupt and ended up as part of Wirgin.
While it bears no model name, I believe this is a Sport, and only because that's what it most resembles from photos on the internet. It's a simple folding camera that takes 120 film. This one was a gift from my maternal grandfather, who acquired it while he was stationed in Germany after World War II.
