Taron 35 II
McKeown's attests to a Taron 35 II from c.1957—which would fall logically between the Taron 35 and the Taron 35 III. It's said to have an enlarged, perhaps albada viewfinder and a self-timer added. This model is not easily tracked down, at least among English-language sources. Some sources may be referring to the Taron VR II.
