Hi, regards from us also.
It is very nice, that you have found a shot with such a rare vehicle from our country.
In the 1960s and 70s, in all of the socialist countries back then, because of the shortage of new consumer goods, there was something of a civil movement, but encouraged from the state, which can be described as a- Do it Yourself movement.
A papers and magazines were printed with detailed instructions and photos of some homebuild projects, so the people can make themselfs things like- sewing maschins, portable radios, light mopeds, yachts, small planes, etc, and of course- cars.
As a result, even in Bulgaria in those years, quiet a number of persons have acomplished the building of some remarkably homogen from a design standpoint, handmade cars.
during that time, in the press I have seen photos of at least 4 or 5 different very well build hadmade bulgarian cars from that era.
But non of the cars on these photos, resambles even slightly this example.
So, there is a big chance, that more photos from this car can be found in some of the printed magazines of that movement, or in some other science and technic BG magazines from the era.
Some of the bulgarian tech magazines from the 60s and 70s, are now digitally scanned and posted on bulgarian cites on the Net, but I dont remember to have seen in these scanned issues, photo of that exact handmade car.
I suppose, that this car is made in any case somewhere after 1967, because the rear lights appear to be the lights from this small car- ZAZ 968, which debuted for the 1966 model year.
https://bg.wikipedia.org/wiki/%D0%97%D0%B0%D0%BF%D0%BE%D1%80%D0%BE%D0%B6%D0%B5%D1%86In regard of the technik, to me this car looks to be with conventional layout- front engine, and rear drive. Possibly Moskvitsch engine if build prior to 1971, or Lada-Jiguli engine, if build later.
The white base registration plate- ПБ /PB- this is the prefix for the city of Plovdiv/ is in any case registration of a Government or Community owned car, because it is white with black letters.
After cirka 1966, and prior to 1986, all State, Government, Community, or all other non-private owned cars in BG, were with white plates, and all private owned cars were with black plates.
Anyway, I havent checked and seen until now, all of the digitally scanned pages ot the different monthly published BG tech magazines from the era rom 1960s to the 1980s, so Im planning to do that in the next months or year.
If a see a picture of this particular car from front, or other pictures and info at all, I will post it here, so you can see in.
Best wishes, Liudmil
