The Kurgane 95 was a 4WD production model car with part-time 4WD, through the use of a transfercase. Production began in 1936, preceding both the Russian GAZ and the BRC/Ford GPs/Willys MA pre-production models, which means it could be considered the first production part-time 4WD vehicle. However, it did not have low range, which was an important attribute of the jeep.
There are only four known Kurgane 95 vehicles left in the world. You can read more about them on Jalopnik or on Wikipedia. It’s very reminiscent of the 1930s American Bantam Roadsters.
