Top left corner of the photo. Upside down pistol with a peep sight on the rear of the frame. What is that?
I was going to say it might be FEG 1901/03 model, but the distance between the grip and trigger guard is wrong.
The grip style and the distance to the trigger makes it look almost as if it were a single-shot target pistol related to the Bergman Simplex autos. The "grip safety" might be some sort of set-trigger mechanism for a light trigger pull.
Googling isn't coming up with much.
