I've looked closely at the photos and thought about this. I'm inclined to think that this was a "one off" custom job.
The chrome looks to be polished, rather than the traditional powder chrome finish that was used. The screw heads also are damaged, which really is an indicator that someone opened the camera at some point.
Also, a close look at the accessory shoe shows some paint, and I wonder if the paint on the upper inside of the rails is black.
In any case, we'll never know. I think it's an interesting camera, for sure.
