This is an old Swedish set (as seen from "lek" for "play" instead of the Danish "leg") that, from the box type, must date from 1955 or 1956. The illustration depicts both sides of the box which is smaller than the standard size - its dimensions are 75x55x18mm and they are shared only by sets 1221, 1222, 1240 and 1241.

The top of the interior drawer shows the contents and is in the 1955 design. The interior and bottom of the inner drawer of the box do not have any decoration. Both box tops are identical.

The contents are five windows and one door without glass (one each of the types manufactured at this time) in vs03. These were made in red, white and dark blue but all the windows are red in this case.
