Kieselbach states in his book that six were built, but Tucek lists only 5:
- the 1931 prototype(license plate PIV 453) pictured above,
- two cars built in 1932 with a modified front and headlights outside the front wings (see picture below),
- another car in 1932 like the other 1932 cars, but dark-coloured and without rear spats,
- one last in 1933 built on a Wikov 40 chassis.
The car in Pal's post might be #5.
