Old monstrosity form a scrap yard needs ID

I wouldn't restore it in a million years, but I would rebuild it using another engine and trans.
{If I was in the market to rebuild something like that, and I liked outfits}
Chunky frame and diff rear end has to be adaptable and make a useful vehicle.

It looks to me to be a Communist era lash up. That front wheel is nothing like a  Bohmerland front wheel, its an artillery wheel off a car, and the forks look as if they could be home made by the look of the welding which is rough even by Bulgarian commie standards.

Its a half and half jobbie.Scrap.

There is no deposit on gas bottles in Bulgaria if that pile is anything to go by.
