The images below show the first type of garage door used in sets 1235 and 1236. The box is that of a Swedish set of 1955/56.

Notice that the door frame does not have studs. To secure the frame vertically, it must be inserted in slitted 1X2 bricks (included in set 1236).

Notice, also, that the pins are on the frame and that they insert in holes in the counterweigths.
