You should try to contact this guy.

He lists the Tower Reflex 65 and shows it as being made by Walz. He also shows an old ad that he states as being the Tower Reflex 64 and 65, but the camera in the ad is the same as your camera but doesn't match his image and description of the Tower Reflex 65.
Interestingly, he lists the Tower Reflex 65 as being incorrectly attributed to Fuji, but the Fujitar lenses on your camera would point towards the camera being made by Fuji or Fujita.
The strap lugs on your camera don't match the Walz made cameras, or any of the more common Japanese made TLRs
The wind and focus knobs look like the ones from my Toyocaflex that was made by Tougodo. They also look very similar to the Fujita made cameras.
The shutter release on your camera is unlike nearly every Japanese made TLR, except the Tower Reflex 44 which was also made by Tougodo.
