Thanks for looking. It's possible it was a short lived product that didn't make it through the war. But being 620 I find interesting. I saw a Franka Rolfix. on eBay that had the exact same shutter and lens, and basic appearance.
It's a post-war camera. The lens was made in 1949 and is coated. The camera was probably made for export to the US by Adox. 620-film was never popular in Europe.
