Just to add a little bit to Gerd's input.....
According to what I found out, there were 17 vehicles made in this "mini series". 5 in 1934, 7 in 1935 and 5 in 1936 for a total of 17.
One of the cars apparently participated in a then well known rallye in 1937 and was known as the "Little Entente" Skoda.
A photo of that car, in a museum, is below.
