Fujiwara

Fujiwara Seisakusho (藤原製作所) is a Japanese camera maker about which very little is known. It made the Oscar Six and Renown Six. In advertisements for these two cameras, its address is given as Arakawa-ku, Minami Senju (荒川区南千住) 2–13, northeast of central Tokyo.

Fujiwara is a surname, and seisakusho means factory.
