The first production Tatra streamliner was the T77, only 249 T77 and T77a models being built over 1934-38.
Despite the small production count, a few T77s survive. I saw a 1935 T77a in May at the Tampa Bay Automobile Museum and took a few few photos of it in a state of preliminary restoration.
Tatra T77a. The main exterior differences are the placement of the headlights on the fenders and the addition of a central light. The museum's 1935 Tatra T77a is in the images below. Click on them to enlarge.
Czech cars drove on the left sides of roads until the 1939 German occupation when German right-side practice was dictated.
