Jeicy Camera Works
The name Jeicy Camera Works is found on the top cover of the Jeicy, a Japanese Leica copy made in the 1950s, of which very few examples were made. The cameras were assembled by Kumagai Genji, former developer of the Nippon wartime Leica copy. This was Kumagai's last attempt at camera production, perhaps as an individual business. The name "Jeicy Camera Works" itself did not correspond to an actual company, and was continuing the tradition of dummy names ending in Camera Works, used in advertising material from the prewar period.
