Designer and creator A.O. GELGAR
The camera's name is a diminutive of its creator's but at present no camera with that engraving has been discovered.
The "Gelveta", later the "Sport" , is a "monument" on more than one level. While surrounded by mystery for a long while, the Sport, in its mass produced version, was also considered the Exakta's rival for the title of "World's first 35-mm reflex camera." We now know that series production of the Sport occurred after Ihagee had begun. However , the camera illustrating the article in the January, 1935 issue of "Sovetskoe Foto" is, beyond a shadow of a doubt, a prototype or pre-series camera. It is the Gelveta. An elegant design appears on the lens cap. It seems to bear the name "Gelveta".
