I've found some info about the car: From Family Archive Justina Wajnikonis-Maciejewska
The car was built on the basis of the Adler Junior. Mrs. Justyna describes it in the following way. "After the end of the war. Dad came into possession of a post-German Adler Junior-it was an "old" car, solidly damaged, but it WAS there and that was the most important thing. The condition of the vehicle required constant repairs and removal of defects which was a never-ending challenge for a student of the Lodz University of Technology and then a freshly minted engineer. Time was moving forward the car was wearing out, but thanks to Innovative repairs camed out by its owner, it was still on the so-called "walk There was only one problem Dad couldn't cope with the car was a three-seater, and his family grew quickly - four children were born. A temporary solution was to put the kids in the trunk, so we traveled to church on Sunday (the trunk lid was lifted while driving up). I was tiny, one of my oldest memories from the time when we still lived in Glowno (we moved to Łódź in 1959) is the sight of the boards on the veranda of our house. "I'm going to build a car
out of these planks." Dad said at the time. Construction began in the autumn of 1958. Dad then made a mock-up (1:1 scale) which was a construction made of slats and boards. It was to be the basis for further construction. He sealed the gaps between the slats and planks with paper on which he laid a layer of clay. After it dried he modeled the clay, put a layer of plaster and chalk on it and began to glue the body of the car on it. To make the body, he used photosensitive paper bought from Wifama-cut into narrow strips, it was glued layer by layer onto the prepared model. At that time, there were no resins, so glue called CERTUS was used for gluing, the disadvantage of which was that it was not waterproof when it rained heavily, the body began to smell bad. After it has completely dried and the bottom lavers of boards, plywood, clay and plaster have been removed, the body remains, which has been additionally smeared with a mixture of polystyrene and tri on the inside and outside, on top of which a laver of fabric has been applied. After it was completely dry, a thin second layer of polystyrene with tri was applied, after which the whole thing
was painted and mounted on the Adler chassis.
In the first year of use, the car only had a windshield, but over time it also got side windows Contrary to my fears, there were no problems with registering a car since 1960 my family had a car registered for 5 people. This is not enough for the needs of a group of sox, which was not a problem at first because the youngest daughter was sitting on her mother's lap. With time, however, we had to change our tactics-one of us dived under the seat at the sight of the militia on the road
We drove the Adler until 1969, when Dad gave it to his friend for one zloty
