Many thanks to Håkan Blomqvist of the Swedish AFU, I have posted the text from Understanding’s Annual general meeting for 1970, 1972, 1973 and 1975. You can find links to them on the Understanding page or under the “Understanding Related” menu along the right hand side of this page.
According to the 1970 meeting minutes there were only nine active units left (first page of the meeting minutes).
Cheers, Sean
