The Minox 110s was introduced in 1974. The internet tells me that this camera was not produced by Minox at all, but by Balda in Germany, who also were also involved in manufacture of the 35EL for Minox. The body is made of Makrolon, which is supposed to be very robust, lightweight and with a glass-like transparency(!) In the case of the 110s, the Makrolon is coloured black and is (hopefully) not transparent. It is though, a bit ‘plasticky’.
