Mulix
The Mulix (マリックス) was a Japanese 6×6 folding camera.
An advertisement for this camera was published in the 29 July 1942 issue of Asahi Graph (found here in this site). The camera pictured in the ad is an ordinary copy of the Ikonta B, with a folding finder, a key to advance the film, strap lugs and a body release. The ad presents two versions. The Mulix I was offered for ¥93 or ¥95 (barely legible), with a f:4.5 lens and slow speeds to 1/4 (barely legible). The Mulix II had slow speeds to 1s and was offered with a f:4.5 lens for ¥125 and with a f:3.5 lens for ¥154. The text of the ad says that the 75mm lenses were of the four-element type. Various Mulix filters were offered to go with the camera, each at ¥5.80.
The only company name is K.K. Kuwata Shōkai (株式会社桑田商会), based in Osaka, probably the distributor's name.
In this article, the katakana script マリックス (marikkusu) has been romanized as "Mulix", because a camera has been advertised for sale by a reputable dealer as a Mulix Six with a 75mm f3.5 Mulixar. No other information has been found.
