Not much is known about this company. KKS is probably short of Komoda Suzuki, a joint venture where Komoda designed modelguns and Suzuki sold them (?). Manufacture was probably done by Marushin Industries, as neither Komoda nor Suzuki did not seem to have their own factory.
The only models I know of are Browning 1910, Walther PPK and Colt SAA. Probably their molds were bought by Marushin, who also released such Browning later.
