I'm not sure what you are asking, Lisa.
The old klickies with fixed wrists were around from 1974 to the early 1980s when they were gradually phased out. 320,000,000 were produced by 1981, so there are still plenty around today! Apart from the very early ones, they all had the date '1974' on their right foot. More information
here.
There are some very useful pictures of the contents of early sets on Klickywelt.de
here (though you need to register on the site to view) and
here.
Plenty of small parts are still available, especially from German sellers. Also many are on offer here in the UK, where they were marketed by the British subsidiary of Marx toys, under the name Playpeople. If there is anything specific you want, let me know, I have quite a lot of old klickies and parts.
