The FOKA cameras were imported from Germany before the Second World War by a Mr. L.J.B. Albers from Rotterdam, who was a dealer of photo and film equipment. He bought them from the Balda factory in Dresden in 1935.
There seem to be several models: the most simple is called Foka Box 0. It is a metal box with a simple meniscus lens and three diaphragm apertures. It has a shutter for Time and Instantaneous and two little reflex finders. It took snaps of 6 x 9 cm on roll film. Like more cameras in the depression years of the 1930s it was available in several colors: black, red, blue, green and beige. It cost fl. 2,95.
The second model is called Foka Box No. 1. It has the same specifications as the previous model, but also has two tripod bushes and can take a cable release or delayed time release. It also has a large frame viewfinder on a side. Price was fl. 3,25. The frame finder did cost an extra fl. 0,60 as did the option to have bright reflex finders instead of the duller ones with a little mirror and ground glass.
The top model is the Foka Box No. 2, with a better Periscopic lens and a build in portrait lens. The usual fixed focus lens could take pics from 3 meters to infinity. The portrait lens reduced this from 0.5 to 3 meters. Price was fl. 4,95 without frame finder or bright reflex finders. For an extra fl. 0,60 it could be adapted to a size of 4 x 6 cm negatives. Cases were available in linen (fl. 0,50), leather (fl. 1,25) and leather with plush lining (fl. 2,25).
So, looking at all the possible combinations of colors and extras there must be a miriad of different Foka boxes around. Let's see what the Foka on the pictures is.
The camera is obviously the Foka Box No. 2, with frame finder and bright reflex finders. Below the lens is a scale to set the distance. On the right is the infinity symbol and on the left a letter P. I guess this means Portrait. On top (you cannot see it on these pics) is a pull up strip. Usally this changes the apertures. Above the shutter release seems to be another pull out thing. I don't know what that is, maybe a yellow filter? Below the shutter release you can see the bush for the cable release.
Above the lens there once used to be a name plate with the text 'Fotohandel Victoria Rotterdam'. That was the name of Albers' company.
