Ooops best when the OP does not fall asleep.....sozza. Yes it is. Audicab wins GLORY choose next pic. Also bonus points for the name of the car engine bay.
I kmow that one, but can't think of the name it was made in Czechoslovakia in its time & competed up the Burg mountain hillclimbs of Austria & Switzerland
Twas indeed a Tatra, supposedly copied by Freddie Pork for his beetle. Bit more of a challenge now, will be expanded next week if stumped. My fav engine btw.
