I also do not see any "Revert" action in the "Details" view, which might indicate I use a wrong version o

Do you need more information? Or is there no answer?

There is no OTB UI function to revert to a previous version in Alfresco.

It can be done programmatically like this: get versionHistory of the node, get the version you want to revert to and re-add that version as the latest version. This does not of course remove any history between the current version and the point you want to revert to.

You could possibly delete the versions from the versionHistory between those two points (meaning that you would not need to do a get and re-add that node). I've never tested this to confirm that it works.

(For example of working with versionHistory look at the code from the Max Version Policy (http://code.google.com/p/alfresco-maxversion-policy/)
