Well, I believe I've found the car featured on a Latvian racing history site.
As I don't speak the language you'll have to bear with me as I try to extract what this car is.
It dates from 1980, was designed along the lines of a Ferrari 312T4 and was built by Indujla Rukuta (Indulis Rukuts?).
Not sure if the car is Estonian or Latvian but it appears to be named Estonia-Rukuts. Then again it may be named Rukuta Estonia-19 Formula?
Here is a photo of the car I found on the site -
