The past? (Jelcz no longer exist, right?)
If you mean the city - no idea.
From Kraków? Not Solaris as they are from Poznań
there were some buses still produced in Jelcz in a section of the former factory just a couple of years ago - I am not sure if it is still true -
That bus was produced in 1970s on a French licence of Berliet factory. In late 1970s and early 1980s it was the main means of public bus transport. The Polish government was critisized for choosing them because they were too delicate for Polish conditions as roads and crowds of passengers contributed to damaged chassis. Also, engines and transmissions caused a lot of problems. The buses weren`t room enough, either.

Despite technical problems, it was a very modern construction at the time.
The bus was chosen by Poland because the French manufacterer was controlled by communist trade unions.
